The Y(4140), X(4260), psi(2D), psi(4S) and tentative psi(3D)  

E-Print Network [OSTI]

Data on B+ --> J/psi phi K+ and the Y(4140) enhancement recently reported by the CDF collaboration [arxiv:0903.2229] are analysed. The threshold behaviour, as well as traces of the X(4260) enhancement, the known c-cbar resonances psi(2D), psi(4S), and a tentative psi(3D) state, as observed in the mass distribution, suggest that the J/psi+phi system has quantum numbers JPC=1--. It is then argued that the Y(4140) enhancement does not represent any kind of resonance, but instead is a natural consequence of the opening of the J/psi+phi channel.

Diffractive J/Psi Production  

SciTech Connect (OSTI)

This work presents measurements of two diffractive production ratio for heavy flavour physics with the use of a reconstructed J/{psi} {yields} {mu}{sup +}{mu}{sup -} sample in p{bar p} collisions at {radical}s = 1.96 TeV using the D0 detector at Fermilab Tevatron. These events were selected using the Luminosity Monitor detectors, the calorimeter system and the muon system in a pseudo-rapidity region with range 2.7 {le} |{eta}| {le} 4.4. The measured ratio were estimated to be N{sub diff}{sup J/{psi}}/N{sub total}{sup J/{psi}} = (1.74 {+-} 0.16(stat) {+-} 0.13(syst))% e N{sub diff}{sup b}/N{sub total}{sup b} = (0.79 {+-} 0.11(stat) {+-} 0.23(syst))%.

POLARIZATION OF MUOPRODUCED J/{psi} (3100)  

SciTech Connect (OSTI)

We have analyzed the polarization and Q{sup 2}-dependence of muoproduced {psi}{yields}{mu}{sup +}{mu}{sup -} in a magnetized-steel calorimeter at Fermilab. The reaction {gamma}{sub V}N{yields}{psi}N is found to be helicity-conserving. Even allowing for possible Q{sup 2}-dependence of the decay angular distribution, the {psi} muoproduction cross section falls more steeply in Q{sup 2} than predicted by {psi} dominance.

Measurement of \\psi(3770) parameters  

E-Print Network [OSTI]

We report the final results of a study of the \\psi(3770) meson using a data sample collected with the KEDR detector at the VEPP-4M electron-positron collider. The data analysis takes into account the interference between the resonant and nonresonant $D\\bar{D}$ production, where the latter is related to the nonresonant part of the energy-dependent form factor $F_D$. The vector dominance approach and several empirical parameterizations have been tried for the nonresonant $F_D^{\\NR}(s)$. Our results for the mass and total width of \\psi(3770) assuming \\psi(2S) dominance in $F_D^{\\NR}(s)$, are M = 3779.1 ^{+1.8}_{-1.7} +-0.6 ^{+0.2}_{-0.3} MeV/c^2, \\Gamma =25.2 ^{+4.6}_{-4.1} +-0.5 ^{+0.5}_{-0.2} MeV, where the first, second and third uncertainties are statistical, systematic and model, respectively. For the electron partial width two possible solutions have been found: (1) \\Gamma_{ee} = 147 ^{+97}_{-62} +- 13 ^{+11}_{-10} eV, (2) \\Gamma_{ee} = 415 ^{+59}_{-58} +- 38 ^{+160}_{-10} eV.

Measurement of \\Gamma_{ee}(J/\\psi)*Br(J/\\psi->e^+e^-) and \\Gamma_{ee}(J/\\psi)*Br(J/\\psi->\\mu^+\\mu^-)  

E-Print Network [OSTI]

The products of the electron width of the J/\\psi meson and the branching fraction of its decays to the lepton pairs were measured using data from the KEDR experiment at the VEPP-4M electron-positron collider. The results are \\Gamma_{ee}(J/\\psi)*Br(J/\\psi->e^+e^-)=0.3323\\pm0.0064\\pm0.0048 keV, \\Gamma_{ee}(J/\\psi)*Br(J/\\psi->\\mu^+\\mu^-)=0.3318\\pm0.0052\\pm0.0063 keV. Assuming e\\mu universality and using the world average value of the lepton branching fraction, we also determine the leptonic \\Gamma_{ll}=5.59\\pm0.12 keV and total \\Gamma=94.1\\pm2.7 keV widths of the J/\\psi meson.

Search for the Invisible Decay of J/{psi} in {psi}(2S){yields}{pi}{sup +}{pi}{sup -}J/{psi}  

SciTech Connect (OSTI)

Using {psi}(2S){yields}{pi}{sup +}{pi}{sup -}J/{psi} events in a sample of 14.0x10{sup 6} {psi}(2S) decays collected with the BES-II detector, a search for the decay of the J/{psi} to invisible final states is performed. No signal is found, and an upper limit at the 90% confidence level is determined to be 1.2x10{sup -2} for the ratio (B(J/{psi}{yields}invisible)/B(J/{psi}{yields}{mu}{sup +}{mu}{sup -})). This is the first search for J/{psi} decays to invisible final states.

J/psi Production in Quark-Gluon Plasma  

E-Print Network [OSTI]

We study J/psi production at RHIC and LHC energies with both initial production and regeneration. We solve the coupled set of transport equation for the J/psi distribution in phase space and the hydrodynamic equation for evolution of quark-gluon plasma. At RHIC, continuous regeneration is crucial for the J/psi momentum distribution while the elliptic flow is still dominated by initial production. At LHC energy, almost all the initially created J\\psis are dissociated in the medium and regeneration dominates the J/psi properties.

Detection of chlorinated aromatic compounds  

DOE Patents [OSTI]

A method for making a composition for measuring the concentration of chloated aromatic compounds in aqueous fluids, and an optical probe for use with the method. The composition comprises a hydrophobic polymer matrix, preferably polyamide, with a fluorescent indicator uniformly dispersed therein. The indicator fluoresces in the presence of the chlorinated aromatic compounds with an intensity dependent on the concentration of these compounds in the fluid of interest, such as 8-amino-2-naphthalene sulfonate. The probe includes a hollow cylindrical housing that contains the composition in its distal end. The probe admits an aqueous fluid to the probe interior for exposure to the composition. An optical fiber transmits excitation light from a remote source to the composition while the indicator reacts with chlorinated aromatic compounds present in the fluid. The resulting fluorescence light signal is reflected to a second optical fiber that transmits the light to a spectrophotometer for analysis.

Calculate the solubility of aromatics  

SciTech Connect (OSTI)

Like naphthenes and paraffins, aromatics are an important hydrocarbon component of fossil fuels. Their physical and thermodynamic property data are valuable to engineers in the chemical process industries. In particular, their solubility in water is becoming more important in engineering and environmental studies because of increasingly stringent regulations regarding health, safety and the environment. In this article the authors present water-solubility data and correlations for aromatics (benzenes) as a function of temperature. These results can be useful for engineers conducting various types of initial studies.

BES Results on J/psi decays and Charmonium Transitions  

E-Print Network [OSTI]

Results are reported based on samples of 58 million $\\jpsi$ and 14 million $\\psip$ decays obtained by the BESII experiment. Improved branching fraction measurements are determined, including branching fractions for $\\jpsi\\to\\ppp$, $\\psip\\ra \\pi^0\\J$, $\\eta\\J$, $\\pi^0 \\pi^0 J/\\psi$, anything $J/\\psi$, and $\\psi(2S)\\ar\\gamma\\chi_{c1},\\gamma\\chi_{c2}\\ar\\gamma\\gamma\\jpsi$. The decay $J/\\psi \\to \\omega \\pi ^+\\pi ^-$ is studied. At low $\\pi \\pi$ mass, a large, broad peak due to the $\\sigma$ is observed, and its pole position is determined. Results are presented on $\\psi(2S)$ and $J/\\psi$ hadronic decays to $K^0_SpK^-\\bar n$ and $K^0_S\\bar p K^+n$ final states. No significant $\\Theta(1540)$ signal, the pentaquark candidate, is observed, and upper limits are set. An enhancement near the $m_p + M_{\\Lambda}$ mass threshold is observed in the $p\\bar{\\Lambda}$ invariant mass spectrum from $J/\\psi \\to p K^- \\bar{\\Lambda} + c.c.$ decays. It can be fit with an S-wave Breit-Wigner resonance with a mass $m=2075\\pm 12 (stat) \\pm 5 (syst)$ MeV and a width of $\\Gamma =90 \\pm 35 (stat) \\pm 9 (syst)$ MeV.

Exclusive photoproduction of J/psi and psi(2S) states in proton-proton collisions at the CERN LHC  

E-Print Network [OSTI]

In this work we investigate the exclusive photoproduction of J/psi and the radially excited psi(2S) state off nucleon in proton-proton collisions. The theoretical framework considered in the analysis is the light-cone dipole formalism and predictions are done for proton-proton collisions at the CERN-LHC energy of 7 TeV. The theoretical uncertainties are investigated and comparison is done to the recent LHCb Collaboration data for the exclusive charmonium production.

Hadronic Production of psi(2S) Cross section and Polarization  

SciTech Connect (OSTI)

The hadronic production cross section and the polarization of {psi}(2S) meson are measured by using the data from p{bar p} collisions at {radical}s = 1.96 TeV collected by the Collider Detector at Fermilab. The datasets used correspond to integrated luminosity of 1.1 fb{sup -1} and 800 pb{sup -1}, respectively. The decay {psi}(2S) {yields} {mu}{sup +}{mu}{sup -} is used to reconstruct {psi}(2S) mesons in the rapidity range |y({psi}(2S))| < 0.6. The coverage of the p{sub T} range is 2.0 GeV/c {le} p{sub T} ({psi}(2S)) < 30 GeV/c for the cross section analysis and pT {ge} 5 GeV/c for the polarization analysis. For events with p{sub T} ({psi}(2S)) > 2 GeV/c the integrated inclusive cross section multiplied by the branching ratio for dimuon decay is 3.17 {+-} 0.04 {+-} 0.28 nb . This result agrees with the CDF Run I measurement considering the increased center-of-mass energy from 1.8 TeV to 1.96 TeV. The polarization of the promptly produced {psi}(2S) mesons is found to be increasingly longitudinal as p{sub T} increases from 5 GeV/c to 30 GeV/c. The result is compared to contemporary theory models.

Measurement of main parameters of the \\psi(2S) resonance

A high-precision determination of the main parameters of the \\psi(2S) resonance has been performed with the KEDR detector at the VEPP-4M e^{+}e^{-} collider in three scans of the \\psi(2S)--\\psi(3770) energy range. Fitting the energy dependence of the multihadron cross section in the vicinity of \\psi(2S) we obtained the mass value which is discussed in a separate paper and the product of the electron partial width by the branching fraction into hadrons \\Gamma_{ee}*B_{h} = 2.233 +- 0.015 +- 0.036 keV. Using the world average values of the electron and hadron branching fractions, one obtains the electron partial width and the total width of \\psi(2S): \\Gamma_{ee} =2.282 +- 0.015 +- 0.037 keV, \\Gamma = 296 +- 2 +- 8 keV. These results are consistent with and more than two times better than any of the previous experiments

New results on nuclear dependence of J/psi and psi' production in 450 GeV pA collisions  

E-Print Network [OSTI]

To understand the reliability of the charmonia suppression as a signature of the Quark-Gluon Plasma formation in nucleus-nucleus collisions it is important first to understand the details of the production of J/psi and psi' in pA interactions and the difference in the suppression of these two states. This report presents the results of the study by the NA50 collaboration of the J/psi and psi' production in pA interactions at 450 GeV beam energy and its dependence on rapidity. It is shown that the psi' suffers more suppression than the J/psi, which is consistent with a similar observation made at 800 GeV beam energy by the E866/NuSea collaboration.

J/psi and psi(2S) production in pp collisions at sqrt(s) = 7 TeV  

SciTech Connect (OSTI)

A measurement of the J/psi and psi(2S) production cross sections in pp collisions at sqrt(s)=7 TeV with the CMS experiment at the LHC is presented. The data sample corresponds to an integrated luminosity of 37 inverse picobarns. Using a fit to the invariant mass and decay length distributions, production cross sections have been measured separately for prompt and non-prompt charmonium states, as a function of the meson transverse momentum in several rapidity ranges. In addition, cross sections restricted to the acceptance of the CMS detector are given, which are not affected by the polarization of the charmonium states. The ratio of the differential production cross sections of the two states, where systematic uncertainties largely cancel, is also determined. The branching fraction of the inclusive B to psi(2S) X decay is extracted from the ratio of the non-prompt cross sections to be: BR(B to psi(2S) X) = (3.08 +/- 0.12(stat.+syst.) +/- 0.13(theor.) +/- 0.42(BR[PDG])) 10^-3

For the isospin violating decays, the upper limits are determined to be B(J/{psi}{yields}{lambda}{lambda}{pi}{sup 0})<6.4x10{sup -5} and B[{psi}(2S){yields}{lambda}{lambda}{pi}{sup 0}]<4.9x10{sup -5} at the 90% confidence level. The isospin conserving process J/{psi}{yields}{lambda}{lambda}{eta} is observed for the first time, and its branching fraction is measured to be B(J/{psi}{yields}{lambda}{lambda}{eta})=(2.62{+-}0.60{+-}0.44)x10{sup -4}, where the first error is statistical and the second one is systematic. No {lambda}{lambda}{eta} signal is observed in {psi}(2S) decays, and B[{psi}(2S){yields}{lambda}{lambda}{eta}]<1.2x10{sup -4} is set at the 90% confidence level. Branching fractions of J/{psi} decays into {sigma}{sup +}{pi}{sup -}{lambda} and {sigma}{sup -}{pi}{sup +}{lambda} are also reported, and the sum of these branching fractions is determined to be B(J/{psi}{yields}{sigma}{sup +}{pi}{sup -}{lambda}+c.c.)=(1.52{+-}0.08{+-}0.16)x10{sup -3}.

Prediction for transverse energy dependence of $J/\\psi$ to Drell-Yan ratio in Au+Au collisions at RHIC energy was obtained in a model which assume 100% absorption of $J/\\psi$ above a threshold density. The threshold density was obtained by fitting the NA50 data on $J/\\psi$ suppression in Pb+Pb collisions at SPS energy. At RHIC energy, hard processes may be important. Prediction of $J/\\psi$ suppression with and without hard processes were obtained. With hard processes included, $J/\\psi$'s are strongly suppressed.

Modcomp MAX IV System Processors reference guide  

SciTech Connect (OSTI)

A user almost always faces a big problem when having to learn to use a new computer system. The information necessary to use the system is often scattered throughout many different manuals. The user also faces the problem of extracting the information really needed from each manual. Very few computer vendors supply a single Users Guide or even a manual to help the new user locate the necessary manuals. Modcomp is no exception to this, Modcomp MAX IV requires that the user be familiar with the system file usage which adds to the problem. At General Atomics there is an ever increasing need for new users to learn how to use the Modcomp computers. This paper was written to provide a condensed Users Reference Guide'' for Modcomp computer users. This manual should be of value not only to new users but any users that are not Modcomp computer systems experts. This Users Reference Guide'' is intended to provided the basic information for the use of the various Modcomp System Processors necessary to, create, compile, link-edit, and catalog a program. Only the information necessary to provide the user with a basic understanding of the Systems Processors is included. This document provides enough information for the majority of programmers to use the Modcomp computers without having to refer to any other manuals. A lot of emphasis has been placed on the file description and usage for each of the System Processors. This allows the user to understand how Modcomp MAX IV does things rather than just learning the system commands.

Observation of B{sup -}{yields}J/{psi}{lambda}p and searches for B{sup -}{yields}J/{psi}{sigma}{sup 0}p and B{sup 0}{yields}J/{psi}pp decays  

SciTech Connect (OSTI)

We report the observation of B{sup -}{yields}J/{psi}{lambda}p and searches for B{sup -}{yields}J/{psi}{sigma}{sup 0}p and B{sup 0}{yields}J/{psi}pp decays, using a sample of 275x10{sup 6} BB pairs collected with the Belle detector at the {upsilon}(4S) resonance. We observe a signal of 17.2{+-}4.1 events with a significance of 11.1{sigma} and obtain a branching fraction of B(B{sup -}{yields}J/{psi}{lambda}p)=11.6{+-}2.8(stat){sub -2.3}{sup +1.8}(sys)x10{sup -6}. No signal is found for either of the two decay modes, B{sup -}{yields}J/{psi}{sigma}{sup 0}p and B{sup 0}{yields}J/{psi}pp, and upper limits for the branching fractions are determined to be B(B{sup -}{yields}J/{psi}{sigma}{sup 0}p)<1.1x10{sup -5} and B(B{sup 0}{yields}J/{psi}pp)<8.3x10{sup -7} at 90% confidence level.

Inclusive J/{psi} Production in {Upsilon} Decay Via Color-Singlet Mechanism  

SciTech Connect (OSTI)

We report the recent works about the inclusive J/{psi} production in {Upsilon} decay. Our results show that until now the color-singlet (CS) contribution which includes leading order ({alpha}{sub s}{sup 5}){Upsilon}{yields}J/{psi}+cc-barg process and {alpha}{sub s}{sup 6} order {Upsilon}{yields}J/{psi}+gg(4g) process as well as {alpha}{sub s}{sup 2{alpha}2} order {Upsilon}{yields}J/{psi}+cc-bar and {Upsilon}{yields}J/{psi}+gg processes can not explain the experimental data yet. A preliminary CS prediction of R{sub cc} (B({Upsilon}{yields}J/{psi}+cc-bar+X)/B({Upsilon}{yields}J/{psi}+X)) 0.39{sub -0.20}{sup +0.21}, which is much larger than color-octet (CO) prediction, is also given as a good quantity to discriminate the CS and color-octet mechanism.

Experimental and modeling investigation of aromatic and polycyclic aromatic hydrocarbon formation in a premixed ethylene flame  

SciTech Connect (OSTI)

Experimental and detailed chemical kinetic modeling has been performed to investigate aromatic and polyaromatic hydrocarbon formation pathways in a rich, sooting, ethylene-oxygen-argon premixed flame. An atmospheric pressure, laminar flat flame operated at an equivalence ratio of 2.5 was used to acquire experimental data for model validation. Gas composition analysis was conducted by an on-line gas chromatograph/mass spectrometer (GC/MS) technique. Measurements were made in the flame and post-flame zone for a number of low molecular weight species, aliphatics, aromatics and polycyclic aromatic hydrocarbons (PAHs) ranging from two to five-aromatic fused rings. The modeling results show the key reaction sequences leading to aromatic and polycyclic aromatic hydrocarbon growth involve the combination of resonantly stabilized radicals. In particular, propargyl and 1-methylallenyl combination reactions lead to benzene and methyl substituted benzene formation, while polycyclic aromatics are formed from cyclopentadienyl radicals and fused rings that have a shared C{sub 5} side structure. Naphthalene production through the reaction step of cyclopentadienyl self-combination and phenanthrene formation from indenyl and cyclopentadienyl combination were shown to be important in the flame modeling study. The removal of phenyl by O{sub 2} leading to cyclopentadienyl formation is expected to play a pivotal role in the PAH or soot precursor growth process under fuel-rich oxidation conditions.

Meson Emission Model of Psi -> N Nbar m Charmonium Strong Decays  

SciTech Connect (OSTI)

In this paper we consider a sequential "meson emission" mechanism for charmonium decays of the type $\\Psi \\to \\NNm$, where $\\Psi$ is a generic charmonium state, $N$ is a nucleon and $m$ is a light meson. This decay mechanism, which may not be dominant in general, assumes that an $\\NN$ pair is created during charmonium annihilation, and the light meson $m$ is emitted from the outgoing nucleon or antinucleon line. A straightforward generalization of this model can incorporate intermediate $N^*$ resonances. We derive Dalitz plot event densities for the cases $\\Psi = \\eta_c$, $J/\\psi$, $\\chi_{c0}$, $\\chi_{c1}$ and $\\psi'$ and $m = \\pi^0, f_0$ and $\\omega$ (and implicitly, any $0^{-+}$, $0^{++}$ or $1^{--}$ final light meson). It may be possible to separate the contribution of this decay mechanism to the full decay amplitude through characteristic event densities. For the decay subset $\\Psi \\to \\pppi$ the two model parameters are known, so we are able to predict absolute numerical partial widths for $\\Gamma(\\Psi\\to \\pppi)$. In the specific case $J/\\psi \\to \\pppi$ the predicted partial width and $M_{p\\pi}$ event distribution are intriguingly close to experiment. We also consider the possibility of scalar meson and glueball searches in $\\Psi \\to \\ppf0$. If the meson emission contributions to $\\Psi \\to \\NNm$ decays can be isolated and quantified, they can be used to estimate meson-nucleon strong couplings $\\{g_{NNm}\\}$, which are typically poorly known, and are a crucial input in meson exchange models of the $NN$ interaction. The determination of $g_{NN\\pi}$ from $J/\\psi \\to \\pppi$ and the (poorly known) $g_{NN\\omega}$ and the anomalous ``strong magnetic" coupling $\\kappa_{NN\\omega}$ from $J/\\psi \\to \\ppw$ are considered as examples.

$J/\\psi$ suppression at FAIR energy collisions and QCD phase diagram  

E-Print Network [OSTI]

Survival probability for $J/\\psi$'s in FAIR energy collisions is studied in a QGP motivated threshold model. In the threshold model $J/\\psi$'s are assumed to dissociate beyond a threshold temperature $T_{J/\\psi}$. Model parameters are obtained by analysing experimental data in $\\snn$=17.4 and 200 GeV collisions. In low energy collisions, model is sensitive to the QCD phase diagram. The model predicts that $J/\\psi$'s are least suppressed in $\\sqrt{s}_{NN}\\approx$ 40 GeV collisions.

Measurement of decay amplitudes of B{yields}J/{psi}K*, {psi}(2S)K*, and {chi}{sub c1}K* with an angular analysis

We perform the first three-dimensional measurement of the amplitudes of B{yields}{psi}(2S)K* and B{yields}{chi}{sub c1}K* decays and update our previous measurement for B{yields}J/{psi}K*. We use a data sample collected with the BABAR detector at the PEP-II storage ring, corresponding to 232x10{sup 6} BB pairs. The longitudinal polarization of decays involving a J{sup PC}=1{sup ++} {chi}{sub c1} meson is found to be larger than that with a 1{sup --} J/{psi} or {psi}(2S) meson. No direct CP-violating charge asymmetry is observed.

Polarization of J / psi and psi(2S) mesons produced in p anti-p collisions at s**(1/2) = 1.96-TeV  

SciTech Connect (OSTI)

The authors have measured the polarizations of J/{psi} and {psi}(2S) mesons as functions of their transverse momentum p{sub T} when they are produced promptly in the rapidity range |y| < 0.6 with p{sub T} {ge} 5 GeV/c. The analysis is performed using a data sample with an integrated luminosity of about 800 pb{sup -1} collected by the CDF II detector. For both vector mesons, they find that the polarizations become increasingly longitudinal as p{sub T} increases from 5 to 30 GeV/c. These results are compared to the predictions of non-relativistic quantum chromo-dynamics and other contemporary models. The polarizations of J/{psi} and {psi}(2S) mesons from B-hadron decays are also reported.

Measurement of direct CP violation in b -> scc and b -> dcc quark transitions using B+ -> J/psiK+ and B+ -> J/psi pi+ decays  

SciTech Connect (OSTI)

This thesis describes the measurement of the direct CP violation in the b {yields} sc{bar c} transition using the decay B{sup +} {yields} J/{psi}K{sup +}, and in the b {yields} dc{bar c} transition using the decay B{sup +} {yields} J/{psi}{pi}{sup +}. The decays of B{sup +} mesons are reconstructed in approximately 2.8 fb{sup -1} of data recorded by D0 detector in 2002-2007 during Run II of Fermilab Tevatron collider. Using the unbinned likelihood fit, a signal of 40,222 {+-} 242 of B{sup +} {yields} J/{psi}K{sup +} and 1,578 {+-} 119 of B{sup +} {yields} J/{psi}{pi}{sup +} events is obtained. The corresponding direct CP violation asymmetries are measured to be A{sub CP}(B{sup +} {yields} J/{psi}(1S)K{sup +}) = +0.0077 {+-} 0.0061(stat.) {+-} 0.0027(syst.), and A{sub CP}(B{sup +} {yields} J/{psi}(1S){pi}{sup +}) = - 0.089 {+-} 0.081(stat.) {+-} 0.028(syst.). The result on A{sub CP} (B{sup +} {yields} J/{psi}(1S)K{sup +}) is consistent with the 2007 world average and is the most precise measurement of this asymmetry, with uncertainty approaching the level of the Standard Model prediction. The result on A{sub CP} (B{sup +} {yields} J/{psi}(1S){pi}{sup +}) constitutes the first measurement of this asymmetry at the hadron collider, with uncertainty at the level of the 2007 world average. The measurement presented in this thesis has become possible due to the sophisticated online and offline tracking/vertexing implemented at D0, and the regular reversal of the polarities of the D0 detector magnets.

Nuclear absorption and anomalous J/psi suppression in Pb+Pb collisions  

E-Print Network [OSTI]

We have studied the J/psi suppression in 158 GeV/c Pb+Pb collisions at CERN SPS. J/psi production is assumed to be a two step process, (i) formation of c bar{c} pair, which is accurately calculable in QCD and (ii) formation of J/psi meson from the c bar{c} pair, which can be conveniently parameterized. In a pA/AA collision, as the c bar{c} pair pass through the nuclear medium, it gains relative square momentum. As a result, some of the c bar{c} pairs can gain enough momentum to cross the threshold to become open charm meson, leading to suppression in pA/AA collisions. The model without any free parameter could describe the of NA50 data on centrality dependence of the ratio's; J/psi over Drell-Yan, J/psi over minimum bias and also the Drell-Yan over minimum bias. The model was used to predict J/psi suppression at RHIC energy. At RHIC energy, hard processes may be important. With hard processes included, J/psi's are strongly suppressed, in agreement with other model calculations. We also show that centrality dependence of J/psi over minimum bias ratio can be used to determine the fraction of hard processes in the collision.

Branching fraction and charge asymmetry measurements in B{yields}J/{psi}{pi}{pi} decays  

SciTech Connect (OSTI)

We study the decays B{sup 0}{yields}J/{psi}{pi}{sup +}{pi}{sup -} and B{sup +}{yields}J/{psi}{pi}{sup +}{pi}{sup 0}, including intermediate resonances, using a sample of 382x10{sup 6} BB pairs recorded by the BABAR detector at the PEP-II e{sup +}e{sup -} B factory. We measure the branching fractions B(B{sup 0}{yields}J/{psi}{rho}{sup 0})=(2.7{+-}0.3{+-}0.2)x10{sup -5} and B(B{sup +}{yields}J/{psi}{rho}{sup +})=(5.0{+-}0.7{+-}0.3)x10{sup -5}. We also set the following upper limits at the 90% confidence level: B(B{sup 0}{yields}J/{psi}{pi}{sup +}{pi}{sup -} nonresonant)<1.2x10{sup -5}, B(B{sup 0}{yields}J/{psi}f{sub 2})<4.6x10{sup -6}, and B(B{sup +}{yields}J/{psi}{pi}{sup +}{pi}{sup 0} nonresonant)<7.3x10{sup -6}. We measure the charge asymmetry in charged B decays to J/{psi}{rho} to be -0.11{+-}0.12{+-}0.08.

Monitoring of vapor phase polycyclic aromatic hydrocarbons  

DOE Patents [OSTI]

An apparatus for monitoring vapor phase polycyclic aromatic hydrocarbons in a high-temperature environment has an excitation source producing electromagnetic radiation, an optical path having an optical probe optically communicating the electromagnetic radiation received at a proximal end to a distal end, a spectrometer or polychromator, a detector, and a positioner coupled to the first optical path. The positioner can slidably move the distal end of the optical probe to maintain the distal end position with respect to an area of a material undergoing combustion. The emitted wavelength can be directed to a detector in a single optical probe 180.degree. backscattered configuration, in a dual optical probe 180.degree. backscattered configuration or in a dual optical probe 90.degree. side scattered configuration. The apparatus can be used to monitor an emitted wavelength of energy from a polycyclic aromatic hydrocarbon as it fluoresces in a high temperature environment.

Removal of trace olefins from aromatic hydrocarbons  

SciTech Connect (OSTI)

A process is described for treating a hydrocarbon process stream by converting trace quantities of olefinic impurities to nonolefinic hydrocarbons. The process comprises contacting the process stream, which contains trace olefins in an amount of from about 50 to about 2000 as measured by Bromine Index and at least 80% by weight of aromatic and naphthenic hydrocarbons having from 6 to 20 carbon atoms per molecule, at reaction conditions which ensure liquid phase operation with a solid catalyst composite comprising a crystalline aluminosilicate zeolite and a refractory inorganic oxide. A catalytic olefin-consuming alkylation reaction then produces an essentially olefinfree product stream with approximately the same quantity and distribution of aromatic and naphthenic hydrocarbons as contained in the process stream.

We study the penguin pollution in the B^0 -> J/psi K_S decay up to leading power in 1/m_b and to next-to-leading order in \\alpha_s, m_b being the b quark mass and \\alpha_s the strong coupling constant. The deviation \\Delta S_{J/psi K_S} of the mixing-induced CP asymmetry from sin(2\\phi_1) and the direct CP asymmetry A_{J/psi K_S} are both found to be of O(10^{-3}) in a formalism that combines the QCD-improved factorization and perturbative QCD approaches.

Aromatics oxidation and soot formation in flames  

SciTech Connect (OSTI)

This project is concerned with the kinetics and mechanisms of aromatics oxidation and soot and fullerenes formation in flames. The scope includes detailed measurements of profiles of stable and radical species concentrations in low-pressure one-dimensional premixed flames. Intermediate species identifications and mole fractions, fluxes, and net reaction rates calculated from the measured profiles are used to test postulated reaction mechanisms. Particular objectives are to identify and to determine or confirm rate constants for the main benzene oxidation reactions in flames, and to characterize fullerenes and their formation mechanisms and kinetics.

Study of Decays $B_d \\to J/\\psi+ K^*$ and $B_s \\to J/\\psi+ \\phi$ with the D0 detector  

SciTech Connect (OSTI)

We present measurements of the linear polarization amplitudes and the strong relative phases that describe the flavor-untagged decays B{sub d} {yields} J/{Psi} K* and B{sub s} {yields} J/{Psi}{phi} in the transversity basis. We also measure the mean lifetime of the B{sub s} mass eigenstates and the lifetime ratio. The analyses are based on approximately 2.8 fb{sup -1} of data recorded with the D0 detector. From our measurements of the angular parameters we conclude that there is no evidence for a deviation from flavor SU(3) symmetry for these decays and that the factorization assumption is not valid for the B{sub d} {yields} J/{Psi} K* decay.

Study of the K+ pi+ pi- Final State in B+ -> J/psi K+ pi+ pi- and B+ -> psi-prime K+ pi+ pi-  

E-Print Network [OSTI]

Using 535 x 10^6 B-meson pairs collected by the Belle detector at the KEKB e+ e- collider, we measure branching fractions of (7.16 +/- 0.10(stat) +/- 0.60(syst)) x 10^-4 for B+ -> J/psi K+ pi+ pi- and (4.31 +/- 0.20(stat) +/- 0.50(syst)) x 10^-4 for B+ -> psi-prime K+ pi+ pi-. We perform amplitude analyses to determine the resonant structure of the K+ pi+ pi- final state in B+ -> J/psi K+ pi+ pi- and B+ -> psi-prime K+ pi+ pi- and find that the K_1(1270) is a prominent component of both decay modes. There is significant interference among the different intermediate states, which leads, in particular, to a striking distortion of the rho line shape due to the omega. Based on the results of the fit to the B+ -> J/psi K+ pi+ pi- data, the relative decay fractions of the K_1(1270) to K rho, K omega, and K^*(892) pi are consistent with previous measurements, but the decay fraction to K_0^*(1430) is significantly smaller. Finally, by floating the mass and width of the K_1(1270) in an additional fit of the B+ -> J/psi K+ pi+ pi- data, we measure a mass of (1248.1 +/- 3.3(stat) +/- 1.4(syst)) MeV/c^2 and a width of (119.5 +/- 5.2(stat) +/- 6.7(syst)) MeV/c^2 for the K_1(1270).

Using a sample of 58 million J/{psi} events collected with the BESII detector at the BEPC, more than 100 000 J/{psi}{yields}pp{pi}{sup 0} events are selected, and a detailed partial wave analysis is performed. The branching fraction is determined to be Br(J/{psi}{yields}pp{pi}{sup 0})=(1.33{+-}0.02{+-}0.11)x10{sup -3}. A long-sought missing N*, first observed in J/{psi}{yields}pn{pi}{sup -}, is observed in this decay too, with mass and width of 2040{sub -4}{sup +3}{+-}25 MeV/c{sup 2} and 230{sub -8}{sup +8}{+-}52 MeV/c{sup 2}, respectively. Its spin-parity favors (3/2){sup +}. The masses, widths, and spin parities of other N* states are obtained as well.

Electron performance with J/$\\psi$ with the ATLAS detector  

E-Print Network [OSTI]

The understanding of the reconstruction of electrons in the ATLAS experiment at LHC is one of the key issues for the 2010 run at a center of mass energy of 7 TeV. Two aspects are of interest: the energy calibration and the reconstruction efficiency. The energy measurement of electrons is based on the electromagnetic calorimeter over most of the relevant energy range (5 GeV to a few TeV). The electromagnetic calorimeter clusters are formed from electronically calibrated calorimeter cells and are corrected for local position and energy variations. A refined calibration procedure, developed and validated over years of test-beam strives to identify all sources of energy losses upstream of the outside the cluster and corrects for them one by one (using Monte Carlo). The present study is aiming at a first validation of this calibration strategy on prompt electrons from known physics processes. The electron reconstruction efficiency can be measured with data using a tag-and-probe approach with J/psi->ee decay...

Elastic properties of superconducting MAX phases from first principles calculations  

E-Print Network [OSTI]

Using first-principles density functional calculations, a systematic study on the elastic properties for all known superconducting MAX phases (Nb2SC, Nb2SnC, Nb2AsC, Nb2InC, Mo2GaC and Ti2InC) was performed. As a result, the optimized lattice parameters, independent elastic constants, indicators of elastic anisotropy and brittle/ductile behavior as well as the so-called machinability indexis were calculated. We derived also bulk and shear moduli, Young's moduli, and Poisson's ratio for ideal polycrystalline MAX aggregates. The results obtained were discussed in comparison with available theoretical and experimental data and elastic parameters for other layered superconductors.

Detoxification of aromatic pollutants by fungal enzymes  

SciTech Connect (OSTI)

Fungal enzymes, such as laccase, peroxidase, and tyrosinase, play a prominent role in catalyzing the transformation of various aromatic compounds in the environment. The enzyme-mediated oxidative coupling reaction results in covalent binding of chlorinated phenols and anilines to soil organic matter or polymerization of the substrates in aquatic systems. Both of these processes are accompanied by a detoxification effect. Therefore, it has been postulated that they be exploited for the treatment of polluted soil and water. The mechanism and efficiency of oxidative coupling in pollutant removal were studied by incubation of chlorinated phenols and anilines with various humic substances or soil and analysis of the reaction products by chromatography and mass and {sup 13}C nuclear magnetic resonance (NMR) spectrometry. The decontamination effect could be enhanced by optimization of the reaction conditions and immobilization of enzymes on solid materials. The results obtained strongly support the concept of using enzymes for control of environmental pollution.

Color-singlet J/{psi} production at O({alpha}{sub s}{sup 6}) in {Upsilon} decay  

SciTech Connect (OSTI)

To clarify the conflict between the theoretical predictions and experimental measurements of the inclusive J/{psi} production in {Upsilon} decay, we consider the {alpha}{sub s}{sup 6} order color-singlet (CS) contributions of processes {Upsilon}{yields}J/{psi}+gg and {Upsilon}{yields}J/{psi}+gggg. Both the branching ratio and the J/{psi} momentum spectrum are calculated, and the branching ratio (4.7x10{sup -4}) is larger than the leading-order contribution ({alpha}{sub s}{sup 5}, {Upsilon}{yields}J/{psi}+ccg). Together with the QCD and QED leading-order contributions considered in our previous work, the CS prediction of the branching ratio for the direct J/{psi} production is Br({Upsilon}{yields}J/{psi}{sub direct}+X)=0.90{sub -0.31}{sup +0.49}x10{sup -4}, which is still about 3.8 times less than the CLEO measurement. We also obtain a preliminary CS prediction of R{sub cc}=(B({Upsilon}{yields}J/{psi}+cc+X)/B({Upsilon}{yields}J/{psi}+X)) and find that the value 0.39{sub -0.20}{sup +0.21} is much larger than the color-octet prediction, and suggest to measure this quality in future experimental analysis.

Radiative decays of the psi prime to all-photon final states  

SciTech Connect (OSTI)

Results of studies of selected radiative decays of the psi' to charmonium and non-charmonium states which decay into photons are presented. These studies were performed using a sample of 1.8 x 10/sup 6/ produced psi''s collected by the Crystal Ball detector at the SPEAR electron-positron storage ring. The branching ratios of the chi/sub 0/, chi/sub 2/, and eta'/sub c/ to two photons have been measured to be (4.5 +- 2.2 +- 2.0) x 10/sup -4/, (9.5 +- 2.9 +- 4.5) x 10/sup -4/ (first errors statistical, second systematic), and <1 x 10/sup -2/ (90% C.L.). The signal from the decay chain psi' ..-->.. ..gamma..chi/sub 0/, chi/sub 0/ ..-->.. ..pi../sup 0/..pi../sup 0/ has been observed with essentially no background. Using the observed line shape of the radiative photon in this reaction, the full width of the psi/sub 0/ has been found to be 8.8 +- 1.3 +- 1.5 MeV/c/sup 2/. In addition, the branching ratios of the chi/sub 0/ and chi/sub 2/ to ..pi../sup 0/..pi../sup 0/ have been measured to be (3.5 +- 0.3 +- 1.2) x 10/sup -3/ and (1.2 +- 0.2 +- 0.4) x 10/sup -3/; the branching ratios of the chi/sub 0/ and chi/sub 2/ to eta eta have been measured to be (2.8 +- 0.9 +- 1.3) x 10/sup -3/ and (8.4 +- 4.2 +- 4.0) x 10/sup -4/. The decays of the psi' to four non-charmonium states have been investigated. The branching ratios and upper limits of these decays have been normalized to the branching ratios of the corresponding decays from the J/psi which have been measured using a sample of 2.2 x 10/sup 6/ produced J/psi's collected by the Crystal Ball detector. The ratios of the psi' branching ratios to the J/psi branching ratios for the final states ..gamma..eta, ..gamma..eta', ..gamma..theta, and ..gamma..f have been measured to be <1.8%, <2.6%, <10 to 15%, and 9 +- 3%. These results are compared with the theoretical expectations of lowest-order quantum chromodynamics potential models. Substantial disagreement is found between theory and experiment.

Measurement of the ratio of the production cross sections times branching fractions of Bc+/- to J/psi pi+/- and B+/- to J/psi K+/- and B(Bc+/- to J/psi pi+/- pi+/- pi-/+)/B(Bc+/- to J/psi pi+/-) in pp collisions at sqrt(s) = 7 TeV  

SciTech Connect (OSTI)

The ratio of the production cross sections times branching fractions (sigma(Bc+) B(Bc+ to J/psi pi+))/ (sigma(B+) B(B+ to J/psi K+)) is studied in proton-proton collisions at a center-of-mass energy of 7 TeV with the CMS detector at the LHC. The kinematic region investigated requires Bc+/- and B+/- mesons with transverse momentum pt > 15 GeV and rapidity abs(y) < 1.6. The data sample corresponds to an integrated luminosity of 5.1 inverse femtobarns. The ratio is determined to be [0.48 +/- 0.05 (stat) +/- 0.03 (syst) +/- 0.05 (tau_{Bc})]% The J/psi pi+/- pi+/- pi-/+ decay mode is also observed in the same data sample. Using a model-independent method developed to measure the efficiency given the presence of resonant behaviour in the three-pion system, the ratio of the branching fractions B(Bc+/- to J/psi pi+/- pi+/- pi-/+) / B(Bc+/- to J/psi pi+/-) is measured to be 2.55 +/- 0.80 (stat) +/- 0.33 (syst) +0.04/-0.01 (tau[Bc+]), consistent with the previous LHCb result.

Study of J/psi->eta phi pi+pi- at BESIII  

E-Print Network [OSTI]

Based on a sample of $2.25\\times 10^{8} J/\\psi$ events taken with the BESIII detector at the BEPCII collider, we present the results of a study of the decay $J/\\psi\\to \\eta \\phi\\pi^{+}\\pi^{-}$. The $Y(2175)$ resonance is observed in the invariant mass spectrum of $\\phi f_{0}(980)$ with a statistical significance of greater than $10\\sigma$. The corresponding mass and width are determined to be $M=2200\\pm 6 \\mathrm{(stat.)} \\pm 5\\mathrm{(syst.)} \\mathrm{MeV}/c^{2}$ and $\\Gamma=104\\pm 15\\mathrm{(stat.)}\\pm 15\\mathrm{(syst.)}$ MeV, respectively, and the product branching fraction is measured to be $\\mathcal{B}(J/\\psi\\to\\eta Y(2175)$, $Y(2175)\\to \\phi f_{0}(980)$, $f_{0}(980)\\to \\pi^{+}\\pi^{-})= (1.20\\pm 0.14\\mathrm{(stat.)}\\pm 0.37 \\mathrm{(syst.)})\\times 10^{-4}$. The results are consistent within errors with those of previous experiments. We also measure the branching fraction of $J/\\psi\\to \\phi f_1(1285)$ with $f_1(1285)\\to \\eta\\pi^{+}\\pi^{-}$ and set upper limits on the branching fractions for $J/\\psi\\to \\phi\\eta(1405)$/$\\phi X(1835)$/$\\phi X(1870)$ with $\\eta(1405)$/$X(1835)$/$X(1870)\\to \\eta\\pi^{+}\\pi^{-}$ at the 90\\% confidence level.

New correlation accurately calculates water solubilities of aromatics  

SciTech Connect (OSTI)

A new correlation calculates reliable aromatics solubilities in water down to very low concentrations. The correlation, based on boiling point, can be used for initial engineering studies. The importance of hydrocarbon solubility in water is increasing because of health, safety, and environmental issues. The paper begins with a discussion of the importance of solubility, even at low concentrations. The new correlation is described, aromatics are compared with paraffins, and the new correlation is compared with the API correlation.

Taking into account an asymmetric photon line shape we obtain: M(eta_c) = (2978.1 +- 1.4 +- 2.0) MeV/c^2, Gamma(eta_c) = (43.5 +- 5.4 +- 15.8) MeV, B(J/psi->eta_c gamma) = (2.59 +- 0.16 +- 0.31)%$.

Emission of polycyclic aromatic hydrocarbons in China  

SciTech Connect (OSTI)

Emission of 16 polycyclic aromatic hydrocarbons (PAHs) listed as U.S. Environmental Protection Agency (U.S. EPA) priority pollutants from major sources in China were compiled. Geographical distribution and temporal change of the PAH emission, as well as emission profiles, are discussed. It was estimated that the total PAH emission in China was 25,300 tons in 2003. The emission profile featured a relatively higher portion of high molecular weight (HMW) species with carcinogenic potential due to large contributions of domestic coal and coking industry. Among various sources, biomass burning, domestic coal combustion, and the coking industry contributed 60%, 20%, and 16% of the total emission, respectively. Total emission, emission density, emission intensity, and emission per capita showed geographical variations. In general, the southeastern provinces were characterized by higher emission density, while those in western and northern China featured higher emission intensity and population-normalized emission. Although energy consumption in China went up continuously during the past two decades, annual emission of PAHs fluctuated depending on the amount of domestic coal consumption, coke production, and the efficiency of energy utilization. 47 refs., 6 figs.

Direct CP Violation in B+ to J/psi K+ Decay as Probe for New Physics  

E-Print Network [OSTI]

Currently there are New Physics hints in mixing-induced CP violation S(phi K0), S(pi0 K0) K+ pi-) differs A(K+ pi0), and maybe even in measured S(J/psi K0) vs prediction from global fit to other data. However, these hints either suffer from experimental uncertainties, or uncertain hadronic corrections, and are not yet unequivocal. Motivated by these hints, however, we point out that a unique probe may be direct CP violation in B to J\\psi K mode. An asymmetry observed at 1% or higher would indicate New Physics.

Cosmological Constraints from the SDSS maxBCG Cluster Catalog  

SciTech Connect (OSTI)

We use the abundance and weak lensing mass measurements of the SDSS maxBCG cluster catalog to simultaneously constrain cosmology and the richness-mass relation of the clusters. Assuming a flat {Lambda}CDM cosmology, we find {sigma}{sub 8}({Omega}{sub m}/0.25){sup 0.41} = 0.832 {+-} 0.033 after marginalization over all systematics. In common with previous studies, our error budget is dominated by systematic uncertainties, the primary two being the absolute mass scale of the weak lensing masses of the maxBCG clusters, and uncertainty in the scatter of the richness-mass relation. Our constraints are fully consistent with the WMAP five-year data, and in a joint analysis we find {sigma}{sub 8} = 0.807 {+-} 0.020 and {Omega}{sub m} = 0.265 {+-} 0.016, an improvement of nearly a factor of two relative to WMAP5 alone. Our results are also in excellent agreement with and comparable in precision to the latest cosmological constraints from X-ray cluster abundances. The remarkable consistency among these results demonstrates that cluster abundance constraints are not only tight but also robust, and highlight the power of optically-selected cluster samples to produce precision constraints on cosmological parameters.

Observation of a Resonancelike Structure in the {pi}{sup +-}{psi}{sup '} Mass Distribution in Exclusive B{yields}K{pi}{sup +-}{psi}{sup '} Decays  

SciTech Connect (OSTI)

A distinct peak is observed in the {pi}{sup {+-}}{psi}{sup '} invariant mass distribution near 4.43 GeV in B{yields}K{pi}{sup {+-}}{psi}{sup '} decays. A fit using a Breit-Wigner resonance shape yields a peak mass and width of M=4433{+-}4(stat){+-}2(syst) MeV and {gamma}=45{sub -13}{sup +18}(stat){sub -13}{sup +30}(syst) MeV. The product branching fraction is determined to be B(B{sup 0}{yields}K{sup {+-}}Z{sup {+-}}(4430))xB(Z{sup {+-}}(4430){yields}{pi}{sup {+-}}{psi}{sup '})=(4.1{+-}1.0(stat){+-}1.4(syst))x10{sup -5}, where Z{sup {+-}}(4430) is used to denote the observed structure. The statistical significance of the observed peak is 6.5{sigma}. These results are obtained from a 605 fb{sup -1} data sample that contains 657x10{sup 6} BB pairs collected near the {upsilon}(4S) resonance with the Belle detector at the KEKB asymmetric energy e{sup +}e{sup -} collider.

Using 5.63 pb{sup -1} of data accumulated at the {psi}(2S) resonance with the CLEO III and CLEO-c detectors corresponding to 3.08x10{sup 6} {psi}(2S) decays, a search is performed for the decay {psi}(2S){yields}{eta}{sub c}{pi}{sup +}{pi}{sup -}{pi}{sup 0} to test a theoretical prediction based upon the assumption that the cc pair in the {psi}(2S) does not annihilate directly into three gluons but rather survives before annihilating.

Penguin pollution in the B^0 -> J/psi K_S decay  

E-Print Network [OSTI]

We present the most complete analysis of the penguin correction to the extraction of the standard-model parameter sin(2\\phi_1) from the B^0 -> J/psi K_S decay up to leading power in 1/m_b and to next-to-leading order in \\alpha_s, \\phi_1 being the weak phase, m_b the b quark mass, and \\alpha_s the strong coupling constant. The deviation \\Delta S_{J/psi K_S} of the mixing-induced CP asymmetry from sin(2\\phi_1) and the direct CP asymmetry A_{J/psi K_S} are both found to be of O(10^{-3}) in a formalism that combines the QCD-improved factorization and perturbative QCD approaches. The above results, different from those of O(10^{-4}) and of O(10^{-2}) obtained in the previous calculations, provide an important standard-model reference for verifying new physics from the B^0 -> J/psi K_S data.

On relevance of triple gluon fusion in $J/\\psi$ hadroproduction  

E-Print Network [OSTI]

A contribution to $J/\\psi$ hadroproduction is analyzed in which the meson production is mediated by three-gluon partonic state, with two gluons coming from the target and one gluon from the projectile. This mechanism involves double gluon density in one of the protons, hence this contribution enters at a non-leading twist. It is, however, relevant due to an enhancement factor coming from large double gluon density at small~$x$. We calculate the three-gluon contribution to $J/\\psi$ hadroproduction within perturbative QCD in the $k_T$-factorization framework. Results are obtained for differential $p_T$-dependent cross-sections for all $J/\\psi$ polarizations and for the sum over the polarization components. The rescattering contribution is found to provide a significant correction to the standard leading twist cross-section at the energies of the Tevatron or the LHC at moderate $p_T$. We suggest $J/\\psi$ production in proton-nucleus collision as a possible probe of the triple gluon mechanism.

Prompt and non-prompt J/psi production in pp collisions at sqrt(s) = 7 TeV  

SciTech Connect (OSTI)

The production of J/psi mesons is studied in pp collisions at sqrt(s)=7 TeV with the CMS experiment at the LHC. The measurement is based on a dimuon sample corresponding to an integrated luminosity of 314 inverse nanobarns. The J/psi differential cross section is determined, as a function of the J/psi transverse momentum, in three rapidity ranges. A fit to the decay length distribution is used to separate the prompt from the non-prompt (b hadron to J/psi) component. Integrated over J/psi transverse momentum from 6.5 to 30 GeV/c and over rapidity in the range |y| < 2.4, the measured cross sections, times the dimuon decay branching fraction, are 70.9 \\pm 2.1 (stat.) \\pm 3.0 (syst.) \\pm 7.8(luminosity) nb for prompt J/psi mesons assuming unpolarized production and 26.0 \\pm 1.4 (stat.) \\pm 1.6 (syst.) \\pm 2.9 (luminosity) nb for J/psi mesons from b-hadron decays.

Radiative decays of the psi(3097) to two meson final states  

SciTech Connect (OSTI)

The MARK III detector operating at the SPEAR storage ring has acquired a sample of 2.7 x 10/sup 6/ produced psi(3097)'s. These events are used to investigate the radiative decays of the psi to two meson final states. Such decays are of topical interest because of the unusual QCD laboratory they provide - of particular interest is the possibility of observing glueball states. The process psi ..-->.. ..gamma pi../sup +/..pi../sup -/ is studied. The f(1270) tensor meson is observed and the helicity structure of its production is measured. The data indicate that helicity 2 is suppressed, in disagreement with lowest order QCD calculations. Evidence is presented for the first observation of the theta(1700) in the ..pi../sup +/..pi../sup -/ final state. The strong, but not complete, suppression of this state in the ..pi pi.. channel, combined with the absence of a J/sup P/ = 2/sup +/ signal in a recent MARK III analysis of psi ..-->.. ..gamma.. rho rho, suggest a very mysterious nature for the theta(1700). The process psi ..-->.. ..gamma..K/sup +/K/sup -/ is also studied. The f'(1515) tensor meson is observed with a branching ratio in agreement with the SU(3) symmetry prediction for the standard two gluon radiative decay diagram with no mixing corrections. The helicity structure of the f'(1515) is measured for the first time, and is found to be similar to that of the f(1270). The theta(1700) is observed with high statistics. Its spin and parity are measured, with the result that J/sup P/ = 2/sup +/ is preferred over J/sup P/ = 0/sup +/ at the 99.9% C.L. In addition, evidence is presented for a remarkable narrow state, designated the xi(2220). Its parameters are measured to be: m = 2.218 +- 0.003 +- 0.010 GeV, GAMMA less than or equal to 0.040 GeV at 95% C.L., and BR(psi ..-->.. ..gamma..xi(2220))BR(xi(2220) ..-->.. K/sup +/K/sup -/) = (5.7 +- 1.9 +- 1.4) x 10/sup -5/.

Measurement of J/psi leptonic width with the KEDR detector  

E-Print Network [OSTI]

We report a new precise determination of the leptonic widths of the J/psi meson performed with the KEDR detector at the VEPP-4M $e^{+}e^{-}$ collider. The measured values of the J/psi parameters are: \\Gamma_{ee}\\times\\Gamma_{ee}/\\Gamma = 0.3323 \\pm 0.0064 (stat.) \\pm 0.0048 (syst.) keV \\Gamma_{ee}\\times\\Gamma_{\\mu\\mu}/\\Gamma=0.3318 \\pm 0.0052 (stat.) \\pm 0.0063 (syst.) keV. Assuming $e\\mu$ universality and using the table value of the branching ratios the leptonic \\Gamma_{ll}= 5.59 \\pm 0.12 keV width and the total \\Gamma=94.1 \\pm 2.7 keV widths were obtained. We also discuss in detail a method to calculate radiative corrections at a narrow resonance.

Inelastic Production of J/psi Mesons in Photoproduction and Deep Inelastic Scattering at HERA  

E-Print Network [OSTI]

A measurement is presented of inelastic photo- and electroproduction of J/psi mesons in ep scattering at HERA. The data were recorded with the H1 detector in the period from 2004 to 2007. Single and double differential cross sections are determined and the helicity distributions of the J/psi mesons are analysed. The results are compared to theoretical predictions in the colour singlet model and in the framework of non-relativistic QCD. Calculations in the colour singlet model using a k_T factorisation ansatz are able to give a good description of the data, while colour singlet model calculations to next-to-leading order in collinear factorisation underestimate the data.

Measurement of prompt psi(2S) to J/psi yield ratios in PbPb and pp collisions at sqrt(s[NN]) = 2.76 TeV  

SciTech Connect (OSTI)

The ratio between the prompt psi(2S) and J/psi yields, reconstructed via their decays into muon pairs, is measured in PbPb and pp collisions at sqrt(s[NN]) = 2.76 TeV. The analysis is based on PbPb and pp data samples collected by CMS at the LHC, corresponding to integrated luminosities of 150 inverse microbarns and 5.4 inverse picobarns, respectively. The double ratio of measured yields, (N[psi(2S)]/N[J/psi])[PbPb] / (N[psi(2S)]/ N[J/psi])[pp], is computed in three PbPb collision centrality bins and two kinematic ranges: one at midrapidity, abs(y) < 1.6, covering the transverse momentum range 6.5 < pt < 30 GeV/c, and the other at forward rapidity, 1.6 < abs(y) < 2.4, extending to lower pt values, 3 < pt < 30 GeV/c. The centrality-integrated double ratio changes from 0.45 +/- 0.13 (stat) +/- 0.07 (syst) in the first range to 1.67 +/- 0.34 (stat) +/- 0.27 (syst) in the second. This difference is most pronounced in the most central collisions.

Search for {psi}(3770){yields}{rho}{pi} at the BESII detector at the Beijing Electron-Positron Collider  

SciTech Connect (OSTI)

Non-DD decay {psi}(3770){yields}{rho}{pi} is searched for using a data sample of (17.3{+-}0.5) pb{sup -1} taken at the center-of-mass energy of 3.773 GeV by the BESII detector at the BEPC. No {rho}{pi} signal is observed, and the upper limit of the cross section is measured to be {sigma}(e{sup +}e{sup -}{yields}{rho}{pi})<6.0 pb at 90% C. L. Considering the interference between the continuum amplitude and the {psi}(3770) resonance amplitude, the branching fraction of {psi}(3770) decays to {rho}{pi} is determined to be B({psi}(3770){yields}{rho}{pi}) set-membership sign (6.0x10{sup -6},2.4x10{sup -3}) at 90% C. L. This is in agreement with the prediction of the S- and D-wave mixing scheme of the charmonium states for solving the '{rho}{pi} puzzle' between J/{psi} and {psi}(2S) decays.

From a study of the resonant substructure in {psi}(4415) decay we conclude that the {psi}(4415){yields}D{sup 0}D{sup -}{pi}{sup +} decay is dominated by {psi}(4415){yields}DD{sub 2}*(2460). We obtain B({psi}(4415){yields}D{sup 0}D{sup -}{pi}{sub nonresonant}{sup +})/B({psi}(4415){yields}DD{sub 2}*(24 = 60){yields}D{sup 0}D{sup -}{pi}{sup +})<0.22 at 90% C.L. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of 673 fb{sup -1}.

Training the Recurrent neural network by the Fuzzy Min-Max algorithm for fault prediction  

SciTech Connect (OSTI)

In this paper, we present a training technique of a Recurrent Radial Basis Function neural network for fault prediction. We use the Fuzzy Min-Max technique to initialize the k-center of the RRBF neural network. The k-means algorithm is then applied to calculate the centers that minimize the mean square error of the prediction task. The performances of the k-means algorithm are then boosted by the Fuzzy Min-Max technique.

Ambient aromatic hydrocarbon measurements at Welgegund, South Africa  

SciTech Connect (OSTI)

Aromatic hydrocarbons are associated with direct adverse human health effects and can have negative impacts on ecosystems due to their toxicity, as well as indirect negative effects through the formation of tropospheric ozone and secondary organic aerosol that affect human health, crop production and regional climate. Measurements were conducted at the Welgegund measurement station (South Africa) that is considered to be a regionally representative background site. However, the site is occasionally impacted by plumes from major anthropogenic source regions in the interior of South Africa, which include the western Bushveld Igneous Complex (e.g. platinum, base metal and ferrochrome smelters), the eastern Bushveld Igneous Complex (platinum and ferrochrome smelters), the Johannesburg-Pretoria metropolitan conurbation (>10 million people), the Vaal Triangle (e.g. petrochemical and industries), the Mpumalanga Highveld (e.g. coal-fired power plants and petrochemical industry) and also a region of anti-cyclonic recirculation of air mass over the interior of South Africa. The aromatic hydrocarbon measurements were conducted with an automated sampler on Tenax-TA and Carbopack-B adsorbent tubes with heated inlet for one year. Samples were collected twice a week for two hours during daytime and two hours 1 during night-time. A thermal desorption unit, connected to a gas chromatograph and a mass 2 selective detector was used for sample preparation and analysis. Results indicated that the 3 monthly median total aromatic hydrocarbon concentrations ranged between 0.01 to 3.1 ppb. 4 Benzene levels did not exceed local air quality standards. Toluene was the most abundant 5 species, with an annual median concentration of 0.63 ppb. No statistically significant 6 differences in the concentrations measured during daytime and night-time were found and no distinct seasonal patterns were observed. Air mass back trajectory analysis proved that the lack of seasonal cycles could be attributed to patterns determining the origin of the air masses sampled. Aromatic hydrocarbon concentrations were in general significantly higher in air masses that passed over anthropocentrically impacted regions. Interspecies correlations and ratios gave some indications of the possible sources for the different aromatic hydrocarbons in the source regions defined in the paper. The highest contribution of aromatic hydrocarbon concentrations to ozone formation potential was also observed in plumes passing over anthropocentrically impacted regions.

THE INFRARED SPECTROSCOPY OF NEUTRAL POLYCYCLIC AROMATIC HYDROCARBON CLUSTERS  

SciTech Connect (OSTI)

The mid-infrared spectra of neutral homogeneous polycyclic aromatic hydrocarbon (PAH) clusters have been computed using density functional theory including an empirical correction for dispersion. The C-H out-of-plane bending modes are redshifted for all the clusters considered in this work. The magnitude of the redshift and the peak broadening are dependent on PAH size, shape, and on the PAH arrangement in the cluster.

Final Technical Report -- Bridging the PSI Knowledge Gap: A Multiscale Approach  

SciTech Connect (OSTI)

The Plasma Surface Interactions (PSI) Science Center formed by the grant undertook a multidisciplinary set of studies on the complex interface between the plasma and solid states of matter. The strategy of the center was to combine and integrate the experimental, diagnostic and modeling toolkits from multiple institutions towards specific PSI problems. In this way the Center could tackle integrated science issues which were not addressable by single institutions, as well as evolve the underlying science of the PSI in a more general way than just for fusion applications. The overall strategy proved very successful. The research result and highlights of the MIT portion of the Center are primarily described. A particular highlight is the study of tungsten nano-tendril growth in the presence of helium plasmas. The Center research provided valuable new insights to the mechanisms controlling the nano-tendrils by developing coupled modeling and in situ diagnostic methods which could be directly compared. For example, the role of helium accumulation in tungsten distortion in the surface was followed with unique in situ helium concentration diagnostics developed. These depth-profiled, time-resolved helium concentration measurements continue to challenge the numerical models of nano-tendrils. The Center team also combined its expertise on tungsten nano-tendrils to demonstrate for the first time the growth of the tendrils in a fusion environment on the Alcator C-Mod fusion experiment, thus having significant impact on the broader fusion research effort. A new form of isolated nano-tendril columns were identified which are now being used to understand the underlying mechanisms controlling the tendril growth. The Center also advanced PSI science on a broader front with a particular emphasis on developing a wide range of in situ PSI diagnostic tools at the DIONISOS facility at MIT. For example the strong suppression of sputtering by the certain combination of light-species plasmas and metals was experimentally studied with independent measurement methods across the Center. This surprising result challenges the universal use of the binary-collision approximation in sputtering predictions and continues to be the subject of study. In order to address this issue MIT developed a new in situ erosion measurement technique based on ion beam analysis which can be used at elevated material temperatures. This exciting new technique is now being used to study material erosion in high performance plasma thrusters for space exploration and is being adopted to fusion experimental devices. This is an indicator of the positive synergies that arise from such a Center, with the research having impact beyond the initial area of study. The Center also served successfully as an organizing force for communication to the science community. The MIT members of the Center provided many high-profile overview presentations at prestigious international conferences and national workshops. The research resulted in three student theses and 24 peer-reviewed publications. PSI research continues to be identified as a critical area for fusion energy.

Di-J/psi Studies, Level 3 Tracking and the D0 Run IIb Upgrade  

SciTech Connect (OSTI)

The D0 detector underwent an upgrade to its silicon vertex detector and triggering systems during the transition from Run IIa to Run IIb to maximize its ability to fully exploit Run II at the Fermilab Tevatron. This thesis describes improvements made to the tracking and vertexing algorithms used by the high level trigger in both Run IIa and Run IIb, as well as a search for resonant di-J/{psi} states using both Run IIa and Run IIb data. Improvements made to the tracking and vertexing algorithms during Run IIa included the optimization of the existing tracking software to reduce overall processing time and the certification and testing of a new software release. Upgrades made to the high level trigger for Run IIb included the development of a new tracking algorithm and the inclusion of the new Layer 0 silicon detector into the existing software. The integration of Layer 0 into the high level trigger has led to an improvement in the overall impact parameter resolution for tracks of {approx}50%. The development of a new parameterization method for finding the error associated to the impact parameter of tracks returned by the high level tracking algorithm, in association with the inclusion of Layer 0, has led to improvements in vertex resolution of {approx}4.5 {micro}m. A previous search in the di-J/{psi} channel revealed a unpredicted resonance at {approx}13.7 GeV/c{sup 2}. A confirmation analysis is presented using 2.8 fb{sup -1} of data and two different approaches to cuts. No significant excess is seen in the di-J/{psi} mass spectrum.

Decays of the {psi}(2S) into vector plus pseudoscalar meson final states have been studied with 14x10{sup 6} {psi}(2S) events collected with the BESII detector. Branching fractions of {psi}(2S){yields}{phi}{eta}, {phi}{eta}{sup '}, and {omega}{eta}{sup '}, and upper limits of {psi}(2S){yields}{phi}{pi}{sup 0} and {omega}{eta} are obtained: B({psi}(2S){yields}{phi}{eta})=(3.3{+-}1.1{+-}0.5)x10{sup -5}, B({psi}(2S){yields}{phi}{eta}{sup '})=(3.1{+-}1.4{+-}0.7)x10{sup -5}, and B({psi}(2S){yields}{omega}{eta}{sup '})=(3.2{sub -2.0}{sup +2.4}{+-}0.7)x10{sup -5}; and B({psi}(2S){yields}{phi}{pi}{sup 0})<0.40x10{sup -5}, and B({psi}(2S){yields}{omega}{eta})<3.1x10{sup -5} at the 90% C.L. These results are used to test the perturbative QCD ''12% rule.''.

Production of mixed flavour heavy quarkonium pair $\\Upsilon(1S) J/\\psi$ at LHC  

E-Print Network [OSTI]

Inclusive production of $\\Upsilon J/\\psi$ pair in proton-proton interation at LHCb is considered. This process is forbidden at leading order of perturbation theory, so such channels as double parton scattering, $\\chi_b\\chi_c$ pair production with subsequent radiative decays of $P$-wave quarkonia, contributions of color-octet states, and NLO corrections are studied in details. For all these channels we present theoretical predictions of total cross sections at LHCb and distributions over different kinematical variables. According to presented in the paper results, double parton interaction gives main contribution to the cross section of the considered reaction.

The branching ratios for the exclusive decays of the heavy quarkonia {psi}(3770) and Y(10580) to a pair of light mesons [{pi}{sup +}{pi}{sup -}, KK-bar, {rho}({omega}){pi}, {rho}({omega}){eta}, {rho}({omega}){eta}', K{sup *}K-bar+c.c, {rho}{sup +}{rho}{sup -}, and K{sup *}K-bar{sup *}] and the branching ratios for the decays {psi}(3770) {sup {yields}} J/{psi} + P(P = {pi}{sup 0}, {eta}) and Y(10580) {sup {yields}} Y(1S) + P(P = {pi}{sup 0},{eta},{eta}'), which involve a heavy quarkonium in the final state, are calculated with allowance for new data on the width of the D*{sup {+-}}(2010) meson and the mass differences between the charged and neutral beauty mesons (B{sup {+-}}, on one hand, and B{sup 0} and B-bar{sup 0}, on the other hand). The calculations are based on the model where the Okubo-Zweig-Iizuka rule is dynamically violated owing to the intermediate state DD-bar(BB-bar) in the case of the {psi}(3770) [Y(10580)] meson. The inclusive annihilation of {psi}(3770) and Y(10580) mesons to light hadrons is discussed.

Engineering Work Plan for the Development of Phased Startup Initiative (PSI) Phases 3 and 4 Test Equipment  

SciTech Connect (OSTI)

A number of tools and equipment pieces are required to facilitate planned test operations during Phases 3 and 4 of the Phased Startup Initiative (PSI). These items will be used in assessing residual canister sludge quantities on cleaned fuel assemblies, sorting coarse and fine scrap fuel pieces, assessing the size distribution of scrap pieces, loading scrap into a canister, and measuring the depth of the accumulated scrap in a canister. This work plan supercedes those previously issued for development of several of these test items. These items will be considered prototype equipment until testing has confirmed their suitability for use in K West Basin. The process described in AP-EN-6-032 will be used to qualify the equipment for facility use. These items are considered non-OCRWM for PSI Phase 3 applications. The safety classification of this equipment is General Service, with Quality Level 0 (for PSI Phase 3).

Method of upgrading oils containing hydroxyaromatic hydrocarbon compounds to highly aromatic gasoline  

DOE Patents [OSTI]

The present invention is a multi-stepped method of converting an oil which is produced by various biomass and coal conversion processes and contains primarily single and multiple ring hydroxyaromatic hydrocarbon compounds to highly aromatic gasoline. The single and multiple ring hydroxyaromatic hydrocarbon compounds in a raw oil material are first deoxygenated to produce a deoxygenated oil material containing single and multiple ring aromatic compounds. Then, water is removed from the deoxygenated oil material. The next step is distillation to remove the single ring aromatic compounds as gasoline. In the third step, the multiple ring aromatics remaining in the deoxygenated oil material are cracked in the presence of hydrogen to produce a cracked oil material containing single ring aromatic compounds. Finally, the cracked oil material is then distilled to remove the single ring aromatics as gasoline.

SciTech Connect (OSTI)

In a study of B{sup +}{yields}J/{psi}{gamma}K{sup +} decays, we find evidence for the radiative decay X(3872){yields}J/{psi}{gamma} with a statistical significance of 3.4{sigma}. We measure the product of branching fractions B(B{sup +}{yields}X(3872)K{sup +}){center_dot}B(X(3872){yields}J/{psi}{gamma})=(3.3{+-}1.0{+-}0.3)x10{sup -6}, where the uncertainties are statistical and systematic, respectively. We also measure the branching fraction B(B{sup +}{yields}{chi}{sub c1}K{sup +})=(4.9{+-}0.2{+-}0.4)x10{sup -4}. These results are obtained from (287{+-}3) million BB decays collected at the {upsilon}(4S) resonance with the BABAR detector at the PEP-II B Factory at SLAC.

We present a measurement of the B{sub c}{sup +} meson lifetime in the decay mode B{sub c}{sup +}{yields}J/{psi}e{sup +}{nu}e using the Collider Detector at Fermilab II detector at the Fermilab Tevatron Collider. From a sample of about 360 pb{sup -1} of p{bar p} collisions at {radical}(s)=1.96 TeV, we reconstruct J/{psi}e{sup +} pairs with invariant mass in the kinematically allowed range 4psi}e<6 GeV/c{sup 2}.

We report the first observation of B{sup {+-}}{yields}{psi}(2S){pi}{sup {+-}}, a Cabibbo- and color-suppressed decay. This analysis is based on 657x10{sup 6} BB events collected at the {upsilon}(4S) resonance with the Belle detector at the KEKB energy-asymmetric e{sup +}e{sup -} collider. The measured branching fraction is (2.44{+-}0.22{+-}0.20)x10{sup -5} and the charge asymmetry is A=0.022{+-}0.085{+-}0.016.

Using a MaxEnt Classifier for the Automatic Content Scoring of Free-Text Responses  

SciTech Connect (OSTI)

Criticisms against multiple-choice item assessments in the USA have prompted researchers and organizations to move towards constructed-response (free-text) items. Constructed-response (CR) items pose many challenges to the education community - one of which is that they are expensive to score by humans. At the same time, there has been widespread movement towards computer-based assessment and hence, assessment organizations are competing to develop automatic content scoring engines for such items types - which we view as a textual entailment task. This paper describes how MaxEnt Modeling is used to help solve the task. MaxEnt has been used in many natural language tasks but this is the first application of the MaxEnt approach to textual entailment and automatic content scoring.

The J/psi trigger-tag for study of weak beauty quark decays at the SSC (Superconducting Super Collider)  

SciTech Connect (OSTI)

The weak decays of beauty hadrons offer a unique opportunity at the SSC to study CP violation in a system other than the neutral kaons and provides a long lever arm for searching for new physics if a strategy can be found for triggering on and identifying these decays. We have determined that the decay sequence B ..-->.. J/psi + X followed by the decay of the J/psi ..-->.. ..mu../sup +/..mu../sup -/ presents an opportunity to both trigger on and to unambiguously distinguish b anti b events from the total cross section events.

Measurement of the CP violating phase beta_s in B_s->J/psi phi decays  

SciTech Connect (OSTI)

The CP violating phase {beta}{sub s}{sup J/{psi}{phi}} is measured in decays of B{sub s}{sup 0} {yields} J/{psi}{phi}. This measurement uses 5.2 fb{sup -1} of data collected in {radical}s = 1.96 TeV p{bar p} collisions at the Fermilab Tevatron with the CDF Run-II detector. CP violation in the B{sub s}{sup 0}-{bar B}{sub s}{sup 0} system is predicted to be very small in the Standard Model. However, several theories beyond the Standard Model allow enhancements to this quantity by heavier, New Physics particles entering second order weak mixing box diagrams. Previous measurements have hinted at a deviation from the Standard Model expectation value for {beta}{sub s}{sup J/{psi}{phi}} with a significance of approximately 2{sigma}. The measurement described in this thesis uses the highest statistics sample available to date in the B{sub s}{sup 0} {yields} J/{psi}{phi} decay channel, where J/{psi} {yields} {mu}{sup +}{mu}{sup -} and {phi} {yields} K{sup +}K{sup -}. Furthermore, it contains several improvements over previous analyses, such as enhanced signal selection, fully calibrated particle ID and flavour tagging, and the inclusion of an additional decay component in the likelihood function. The added decay component considers S-wave states of KK pairs in the B{sub s}{sup 0} {yields} J/{psi} K{sup +}K{sup -} channel. The results are presented as 2-dimensional frequentist confidence regions for {beta}{sub s}{sup J/{psi}{phi}} and {Delta}{Lambda} (the width difference between the B{sub s}{sup 0} mass eigenstates), and as a confidence interval for {beta}{sub s}{sup J/{psi}{phi}} of [0.02,0.52] {union} [1.08, 1.55] at the 68% confidence level. The measurement of the CP violating phase obtained in this thesis is complemented by the world's most precise measurement of the lifetime {tau}{sub s} = 1.53 {+-} 0.025 (stat.) {+-} 0.012 (syst.) ps and decay width difference {Delta}{Lambda} = 0.075 {+-} 0.035 (stat.) {+-} 0.01 (syst.) ps{sup -1} of the B{sub s}{sup 0} meson, with the assumption of no CP violation.

Occurrence of chlorinated polynuclear aromatic hydrocarbons in tap water  

SciTech Connect (OSTI)

Organic compounds in tap waters were extracted by a modified continuous liquid-liquid extractor and analyzed by computerized gas chromatography/mass spectrometry using a fused silica capillary column. The results indicate the presence of monochlorinated derivatives of naphthalene, dibenzofuran, fluorene, fluorenone, phenanthrene, and fluoranthene and dichlorinated derivatives of naphthalene, phenanthrene, and fluoranthene. The parent polynuclear aromatic hydrocarbons (PAHs) and their oxygenated derivatives such as fluorenone and anthraquinone were also found. It was demonstrated that chlorinated PAHs (Cl-PAHs) were really present in tap waters at 10/sup -1/-10/sup -2/ ng/L levels.

J/psi production at high transverse momenta in p+p and Cu+Cu collisions at sqrt sNN = 200 GeV  

SciTech Connect (OSTI)

The STAR collaboration at RHIC presents measurements of J/{psi} {yields} e{sup +}e{sup -} at mid-rapidity and high transverse momentum (p{sub T} > 5 GeV/c) in p+p and central Cu+Cu collisions at {radical}sNN = 200 GeV. The inclusive J/{psi} production cross section for Cu+Cu collisions is found to be consistent at high p{sub T} with the binary collision-scaled cross section for p+p collisions, in contrast to previous measurements at lower p{sub T}, where a suppression of J/{psi} production is observed relative to the expectation from binary scaling. Azimuthal correlations of J/{psi} with charged hadrons in p+p collisions provide an estimate of the contribution of B-meson decays to J/{psi} production of 13% {+-} 5%.

First measurements of J/{psi} decays into {sigma}{sup +}{sigma}{sup -} and {xi}{sup 0}{xi}{sup 0}  

SciTech Connect (OSTI)

Based on 58x10{sup 6} J/{psi} events collected with the BESII detector at the Beijing Electron-Positron Collider, the baryon pair processes J/{psi}{yields}{sigma}{sup +}{sigma}{sup -} and J/{psi}{yields}{xi}{sup 0}{xi}{sup 0} are observed for the first time. The branching fractions are measured to be B(J/{psi}{yields}{sigma}{sup +}{sigma}{sup -})=(1.50{+-}0.10{+-}0.22)x10{sup -3} and B(J/{psi}{yields}{xi}{sup 0}{xi}{sup 0})=(1.20{+-}0.12{+-}0.21)x10{sup -3}, where the first errors are statistical and the second ones are systematic.

{CP} Violation in Flavor Tagged $B_s \\to J/\\psi \\phi$ Decays  

SciTech Connect (OSTI)

In this dissertation, we present the results of a time-dependent angular analysis of B{sub s} {yields} J/{psi}{phi} decays performed with the use of initial-state flavor tagging. CP violation is observed in this mode through the interference of decay without net mixing and decay with net mixing, that is, B{sub s} {yields} J/{psi}{phi} and B{sub s} {yields} {bar B}{sub s} {yields} J/{psi}{phi}. The time-dependent angular analysis is used to extract the decay widths of the heavy and light B{sub s} eigenstates and the difference between these decay widths {Delta}{Lambda}{sub s} {triple_bond} {Lambda}{sub s}{sup L}-{Lambda}{sub s}{sup H}. Initial-state flavor tagging is used to determine the matter-antimatter content of the B{sub s} mesons at production time. We combine flavor tagging with the angular analysis, which statistically determines the contributions of the CP-even and CP-odd components at decay time, to measure the CP-violating phase {beta}{sub s}. The phase {beta}{sub s} is expressed in terms of elements of the Cabibbo-Kobayashi-Maskawa matrix as {beta}{sub s} {triple_bond} arg (-V{sub ts}V*{sub tb}/V{sub cs}V*{sub cb}), and is predicted by the Standard Model to be close to zero, {beta}{sub s}{sup SM} = 0.02. In the measurement of {Delta}{Lambda}{sub s}, we use a dataset corresponding to 1.7 fb{sup -1} of luminosity, collected at the CDF experiment from proton-antiproton collisions at a center of mass energy {radical}s = 1.96 TeV. In the measurement of {beta}{sub s}, we use a dataset corresponding to 1.3 fb{sup -1} of collected luminosity. We measure {Delta}{Lambda}{sub s} = (0.071{sub -0.059}{sup +0.064} {+-} 0.007) ps{sup -1} using the time-dependent angular analysis. Combining the angular analysis with flavor-tagging, we find that assuming the Standard Model predictions of {beta}{sub s} and {Delta}{Lambda}{sub s}, the probability of a deviation as large as the level of the observed data is 33%. We obtain a suite of associated results which are discussed in detail in this dissertation alongside the main results.

From a Dalitz plot analysis of B{yields}K{pi}{sup +}{psi}{sup '} decays, we find a signal for Z(4430){sup +}{yields}{pi}{sup +}{psi}{sup '} with a mass M=(4443{sub -12-13}{sup +15+19}) MeV/c{sup 2}, width {gamma}=(107{sub -43-56}{sup +86+74}) MeV, product branching fraction B(B{sup 0}{yields}K{sup -}Z(4430){sup +})xB(Z(4430){sup +}{yields}{pi}{sup +}{psi}{sup '})=(3.2{sub -0.9-1.6}{sup +1.8+5.3})x10{sup -5}, and significance of 6.4{sigma} that agrees with previous Belle measurements based on the same data sample. In addition, we determine the branching fraction B(B{sup 0}{yields}K*(892){sup 0}{psi}{sup '})=(5.52{sub -0.32-0.58}{sup +0.35+0.53})x10{sup -4} and the fraction of K*(892){sup 0} mesons that are longitudinally polarized f{sub L}=(44.8{sub -2.7-5.3}{sup +4.0+4.0})%.

Study of B{yields}J/{psi}{eta}{sup (')} decays and determination of {eta}-{eta}{sup '} mixing angle  

SciTech Connect (OSTI)

We study B{yields}J/{psi}{eta}{sup (')} decays and suggest two methods to determine the {eta}-{eta}{sup '} mixing angle. We calculate not only the factorizable contribution in the QCD factorization scheme but also the nonfactorizable hard spectator corrections in the pQCD approach. We get the branching ratio of B{yields}J/{psi}{eta}, which is consistent with recent experimental data, and predict the branching ratio of B{yields}J/{psi}{eta}{sup '} to be 7.59x10{sup -6}. Two methods for determining the {eta}-{eta}{sup '} mixing angle are suggested in this paper. For the first method, we get the {eta}-{eta}{sup '} mixing angle to be about -13.1 deg., which is consistent with others in the literature. The second method depends on fewer parameters and can thus be used to determine the {eta}-{eta}{sup '} mixing angle with better accuracy but needs, as an input, the branching ratio for B{yields}J/{psi}{eta}{sup '}, which should be measured in the near future.

This thesis describes a measurement of the average proper decay time of the B{sub c}{sup {+-}} mesons, the ground state of bottom and charm quark bound states. The lifetime measurement is carried out in the decay modes B{sub c}{sup {+-}} {yields} J/{psi} + e{sup {+-}} + X and B{sub c}{sup {+-}} {yields} J/{psi} + {mu}{sup {+-}} + X, where the J/{psi} decays as J/{psi} {yields} {mu}{sup +}{mu}{sup -} and the X are unmeasured particles such as {nu}{sub e} or {nu}{sub {mu}}. The data are collect by the CDF II detector which measures the properties of particles created in {radical}s = 1.96 TeV p{bar p} collisions delivered by the Fermilab Tevatron. This measurement uses {approx} 1 fb{sup -1} of integrated luminosity. The measured average proper decay time of B{sub c}{sup {+-}} mesons, {tau} = 0.475{sub -0.049}{sup +0.053}(stat.) {+-} 0.018(syst.) ps, is competitive with the most precise measurements in the world and confirms previous measurements and theoretical predictions.

In this context, a specially developed X-band structure with integrated alignment monitors will be used to mitigate the nonlinearities in the longitudinal phase space due to the second order RF time curvature and the second order momentum compaction term of chicane compressor. The knowledge of the transverse and longitudinal short range wakefields in the X-band structure is essential to evaluate the beam quality in terms of longitudinal energy spread and transverse kick spread. We have used the ABCI code to numerically evaluate the transverse and longitudinal wake potentials for short bunches in this structure

Characteristics of the Neutron Irradiation Facilities of the PSI Calibration Laboratory  

SciTech Connect (OSTI)

The neutron radiation fields of the Calibration Laboratory at Paul Scherrer Institute (PSI) are traceable to the national standards of the Physikalisch-Technische Bundesanstalt (PTB) in Germany. A Berthold LB6411 neutron dose rate meter for neutron radiation is used as a secondary standard. Recently, a thorough characterization of the neutron irradiation fields of the {sup 241}Am-Be and {sup 252}Cf sources by means of reference measurements and a detailed MCNPX simulation of the irradiation facility has been initiated. In this work, the characteristics of the neutron radiation fields are summarized and presented together with model equations and an uncertainty analysis. MCNPX results are shown for the {sup 241}Am-Be source. A comparison of measured and simulated data shows an excellent agreement. From the simulation, valuable information about the neutron fields like the contribution of scattered neutrons in the fields and the energy spectra could be obtained.

$J/\\psi$ production and suppression in high energy proton-nucleus collisions  

E-Print Network [OSTI]

We apply a Color Glass Condensate+Non-Relativistic QCD (CGC+NRQCD) framework to compute $J/\\psi$ production in deuteron-nucleus collisions at RHIC and proton-nucleus collisions at the LHC. Our results match smoothly at high $p_\\perp$ to a next-to-leading order perturbative QCD + NRQCD computation. Excellent agreement is obtained for $p_\\perp$ spectra at RHIC and LHC for central and forward rapidities, as well as for the normalized ratio $R_{pA}$ of these results to spectra in proton-proton collisions. In particular, we observe that the $R_{pA}$ data is strongly bounded by our computations of the same for each of the individual NRQCD channels; this result provides strong evidence that our description is robust against uncertainties in initial conditions and hadronization mechanisms.

Gas and Particulate Sampling of Airborne Polycyclic Aromatic Compounds  

SciTech Connect (OSTI)

The denuder surfaces of the gas and particle (GAP) sampler (developed at the Atmospheric Environment Service of Environment Canada) have been modified by coating with XAD-4 resin, using techniques developed at Lawrence Berkeley National Laboratory (LBNL) for the lower capacity integrated organic vapor/particle sampler (IOVPS). The resulting high capacity integrated organic gas and particle sampler (IOGAPS) has been operated in ambient air at 16.7 L min{sup -1} for a 24-hour period in Berkeley, California, USA. Simultaneous measurements were made at the same collection rate with a conventional sampler that used a filter followed by two sorbent beds. Gas and particle partition measurements were determined for 13 polycyclic aromatic hydrocarbons (PAH) ranging from 2-ring to 6-ring species. The IOGAPS indicated a higher particle fraction of these compounds than did the conventional sampler, suggesting that the conventional sampler suffered from 'blow-off' losses from the particles collected on the filter.

Measurement of the J/Psi Production Cross Section in 920 GeV/c Fixed-Target Proton-Nucleus Interactions  

E-Print Network [OSTI]

The mid-rapidity (dsigma_(pN)/dy at y=0) and total sigma_(pN) production cross sections of J/Psi mesons are measured in proton-nucleus interactions. Data collected by the HERA-B experiment in interactions of 920 GeV/c protons with carbon, titanium and tungsten targets are used for this analysis. The J/Psi mesons are reconstructed by their decay into lepton pairs. The total production cross section obtained is sigma_(pN)(J/Psi) = 663 +- 74 +- 46 nb/nucleon. In addition, our result is compared with previous measurements.

Diesel fuel aromatic and cetane number effects on combustion and emissions from a prototype 1991 diesel engine  

SciTech Connect (OSTI)

This book reports on a prototype 1991-model diesel engine that was tested using EPA transient emissions procedures to determine the effect of fuel properties on combustion characteristics and exhaust emissions. The eleven test fuel set focused primarily on total aromatic content, multi-ring aromatic content, and cetane number, but other fuel variables were also studied. Hydrotreating was used to obtain reductions in fuel sulfur and aromatic content. Increasing cetane number and reducing aromatic content resulted in lower emissions of hydrocarbons and NO{sub x}. Particulate emission were best predicted by sulfur content, aromatic content and 90% distillation temperature. Multi-ring aromatics showed a greater significance that total aromatics on hydrocarbon and particulate emissions. combustion parameters were highly dependent on fuel cetane number.

J/{psi} Production in {radical}(s{sub NN})=200 GeV Cu+Cu Collisions  

SciTech Connect (OSTI)

Yields for J/{psi} production in Cu+Cu collisions at {radical}(s{sub NN})=200 GeV have been measured over the rapidity range |y|<2.2 and compared with results in p+p and Au+Au collisions at the same energy. The Cu+Cu data offer greatly improved precision over existing Au+Au data for J/{psi} production in collisions with small to intermediate numbers of participants, in the range where the quark-gluon plasma transition threshold is predicted to lie. Cold nuclear matter estimates based on ad hoc fits to d+Au data describe the Cu+Cu data up to N{sub part}{approx}50, corresponding to a Bjorken energy density of at least 1.5 GeV/fm{sup 3}.

Evidence for CP Violation in B{sup 0}{yields}J/{psi}{pi}{sup 0} Decays  

SciTech Connect (OSTI)

We present measurements of the branching fraction and time-dependent CP asymmetries in B{sup 0}{yields}J/{psi}{pi}{sup 0} decays based on 466x10{sup 6} {upsilon}(4S){yields}BB events collected with the BABAR detector at the SLAC PEP-II asymmetric-energy B factory. We measure the CP asymmetry parameters S=-1.23{+-}0.21(stat){+-}0.04(syst) and C=-0.20{+-}0.19(stat){+-}0.03(syst), where the measured value of (S, C) is 4.0 standard deviations from (0, 0) including systematic uncertainties. The branching fraction is determined to be B(B{sup 0}{yields}J/{psi}{pi}{sup 0})=[1.69{+-}0.14(stat){+-}0.07(syst)]x10{sup -5}.

Higher-order multipole amplitude measurement in {psi}{sup '}{yields}{gamma}{chi}{sub c2}  

SciTech Connect (OSTI)

Using 106x10{sup 6} {psi}{sup '} events collected with the BESIII detector at the BEPCII storage ring, the higher-order multipole amplitudes in the radiative transition {psi}{sup '}{yields}{gamma}{chi}{sub c2}{yields}{gamma}{pi}{sup +}{pi}{sup -}/{gamma}K{sup +}K{sup -} are measured. A fit to the {chi}{sub c2} production and decay angular distributions yields M2=0.046{+-}0.010{+-}0.013 and E3=0.015{+-}0.008{+-}0.018, where the first errors are statistical and the second systematic. Here M2 denotes the normalized magnetic quadrupole amplitude and E3 the normalized electric octupole amplitude. This measurement shows evidence for the existence of the M2 signal with 4.4{sigma} statistical significance and is consistent with the charm quark having no anomalous magnetic moment.

Noncovalent ????? interaction between graphene and aromatic molecule: Structure, energy, and nature  

SciTech Connect (OSTI)

Noncovalent ????? interactions between graphene and aromatic molecules have been studied by using density functional theory with empirical dispersion correction (?B97X-D) combined with zeroth-order symmetry adapted perturbation theory (SAPT0). Excellent agreement of the interaction energies computed by means of ?B97X-D and spin component scaled (SCS) SAPT0 methods, respectively, shows great promise for the two methods in the study of the adsorption of aromatic molecules on graphene. The other important finding in this study is that, according to SCS-SAPT0 analyses, ????? interactions between graphene and aromatic molecules are largely dependent on both dispersion and electrostatic type interactions. It is also noticed that ????? interactions become stronger and more dispersive (less electrostatic) upon substitution of the very electronegative fluorine atoms onto the aromatic molecules.

J/{psi} measurements in 7 TeV p-p collisions with ALICE using EMCal-triggered events  

SciTech Connect (OSTI)

J/{psi} measurements can be performed with the ALICE experiment through the dilepton decay into e{sup -}e{sup +} (for rapidity Double-Vertical-Line y Double-Vertical-Line <0.9) and {mu}{sup -}{mu}{sup +} (for rapidity -4.0psi} measurements, since it provides electron/hadron discrimination for higher p{sub T} values in comparison to other electron PID techniques in ALICE. The EMCal can also provide fast triggers for events containing high energy electrons. In 2011, during proton-proton collisions at 7 TeV, the ALICE EMCal trigger was intensively used for event selection of showers above 4.8 GeV. In this work, some results from 2011 proton-proton collisions are presented, showing a J/{psi} measurement for transversal momentum above 6 GeV/c, due to a combination of the ALICE EMCal PID and trigger system.

Measurement of the time-dependent CP asymmetries in $B_s^0\\rightarrow J/\\psi K_{\\rm S}^0$  

E-Print Network [OSTI]

The first measurement of decay-time-dependent CP asymmetries in the decay $B_s^0\\rightarrow J/\\psi K_{\\rm S}^0$ and an updated measurement of the ratio of branching fractions $\\mathcal{B}(B_s^0\\rightarrow J/\\psi K_{\\rm S}^0)/\\mathcal{B}(B_d^0\\rightarrow J/\\psi K_{\\rm S}^0)$ are presented. The results are obtained using data corresponding to an integrated luminosity of 3.0 fb$^{-1}$ of proton-proton collisions recorded with the LHCb detector at centre-of-mass energies of 7 and 8 TeV.

Measurement of the B0 ---> Psi (2S) Lambda0 Branching Fraction on BaBar at the Stanford Linear Accelerator Center (Abstract Only)  

SciTech Connect (OSTI)

The decays of B{sup 0} mesons to hadronic final states remains a rich area of physics on BaBar. Not only do the c{bar c}-K final states (e.g. B{sup 0} {yields} {psi}(2S)K{sup 0}) allow for the measurement of CP Violation, but the branching fractions provide a sensitive test of the theoretical methods used to account for low energy non-perturbative QCD effects. They present the measurement of the branching fraction for the decay B{sup 0} {yields} {psi}(2S)K{sub s}. The data set consists of 88.8 {+-} 1.0 x 10{sup 6} B{bar b} pairs collected on the e{sup +}e{sup -} {yields} {Upsilon}(4S) resonance on BaBar/PEP-II at the Stanford Linear Accelerator Center (SLAC). This analysis features a modification of present cuts, with respect to those published so far on BaBar, on the K{sub S} {yields} {pi}{sup +}{pi}{sup -} and {psi}(2S) {yields} J/{psi}{pi}{sup +}{pi}{sup -} which aim at reducing the background while keeping the signal intact. Various data selection criteria are studied for the lepton modes (e{sup +}e{sup -} and {mu}{sup +}{mu}{sup -}) of the J/{psi} and {psi}(2S) to improve signal purity as well as study the stability of the resultant branching fractions.

Polycyclic aromatic hydrocarbons and fatal ischemic heart disease  

SciTech Connect (OSTI)

Several toxicologic and epidemiologic studies have produced evidence that occupational exposure to polycyclic aromatic hydrocarbons (PAH) is a risk factor for ischemic heart disease (IHD). However, a clear exposure-response relation has not been demonstrated. We studied a relation between exposure to PAH and mortality from IHD (418 cases) in a cohort of 12,367 male asphalt workers from Denmark, Finland, France, Germany, Israel, The Netherlands and Norway. Exposures to benzo(a)pyrene were assessed quantitatively using measurement-driven exposure models. Exposure to coal tar was assessed in a semiquantitative manner on the basis of information supplied by company representatives. We carried out sensitivity analyses to assess potential confounding by tobacco smoking. Both cumulative and average exposure indices for benzo(a)pyrene were positively associated with mortality from IHD. The highest relative risk for fatal IHD was observed for average benzo(a)pyrene exposures of 273 ng/m{sup 3} or higher, for which the relative risk was 1.64(95% confidence interval = 1.13-2.38). Similar results were obtained for coal tar exposure. Sensitivity analysis indicated that even in a realistic scenario of confounding by smoking, we would observe approximately 20% to 40% excess risk in IHD in the highest PAH-exposure categories. Our results lend support to the hypothesis that occupational PAH exposure causes fatal IHD and demonstrate a consistent exposure-response relation for this association.

A Multiscale Study of Polycyclic Aromatic Hydrocarbon Properties in Galaxies  

E-Print Network [OSTI]

In the present contribution, I summarize a systematic study of ISO and Spitzer mid-IR spectra of Galactic regions and star forming galaxies. This study quantifies the relative variations of the main aromatic features inside spatially resolved objects as well as among the integrated spectra of 50 objects. Our analysis implies that the properties of the PAHs are remarkably universal throughout our sample and at different spatial scales. In addition, the relative variations of the band ratios, as large as one order of magnitude, are mainly controled by the fraction of ionized PAHs. In particular, I show that we can rule out both the modification of the PAH size distribution and the mid-IR extinction, as an explanation of these variations. High values of the I(6.2)/I(11.3) ratio are found to be associated with the far-UV illuminated surface of PDRs, at the scale of an interstellar cloud, and associated with star formation activity, at the scale of a galaxy. Using a few well-studied Galactic regions, we provide an empirical relation between the I(6.2)/I(11.3) ratio and the ionization/recombination ratio G0/ne. Finally, I show that these trends are consistent with the detailed modeling of the PAH emission within photodissociation regions, taking into account the radiative transfer, the stochastic heating and the charge exchange between gas and dust.

Comparative analysis of polycyclic aromatic sulfur heterocycles isolated from four shale oils. [Polycyclic aromatic sulfur heterocycles; thiophenes  

SciTech Connect (OSTI)

This report describes the isolation of sulfur heterocycle fractions from four shale oils (Paraho, Geokinetics, Occidental, and Rio Blanco), the use of capillary column gas chromatography and mass spectrometry for the identification of individual mixture components, and a reverse (Ames) and forward mutation assay with Salmonella typhimurium to screen for possible health hazards. The major components of the Polycyclic Aromatic Sulfur Heterocycles (PASH) fractions for all four shale oils were found to be two- to three-ringed parent and alkylated thiophene compounds. In all cases the PASH fractions showed no more specific mutagenic response than the neutral PAC fractions from which they were isolated. The only mutagenic response which was detected in the PASH fractions was for the Rio Blanco shale oil and showed specific mutagenic response similar to the neutral PAC fraction from which it was isolated. Finally, the forward mutation 8-azaguanine test was apparently more sensitive than the Ames histidine reversion test in detecting mutagenic activity for the chemical fractions from the shale oils.

Measurement of BR(Bu to phi K)/BR(Bu to J/psi K) at the collider detector at Fermilab  

SciTech Connect (OSTI)

This thesis presents evidence for the decay mode B{sup {+-}} {yields} {phi}K{sup {+-}} in p{bar p} collisions at {radical}s = 1.96 TeV using (120 {+-} 7)pb{sup -1} of data collected by the Collider Detector at Fermilab (CDF). This signal is then used to measure the branching ratio relative to the decay mode B{sup {+-}} {yields} J/{psi}K{sup {+-}}. The measurement starts from reconstructing the two decay modes: B{sup {+-}} {yields} {phi}K{sup {+-}}, where {phi} {yields} K{sup +}K{sup -} and B{sup {+-}} {yields} J/{psi}K{sup {+-}}, where J/{psi} {yields} {mu}{sup +}{mu}{sup -}. The measurement yielded 23 {+-} 7 B{sup {+-}} {yields} {phi}K{sup {+-}} events, and 406 {+-} 26 B{sup {+-}} {yields} J/{psi}K{sup {+-}} events. The fraction of B{sup {+-}} {yields} J/{psi}K{sup {+-}} events where the J/{psi} subsequently decayed to two muons (as opposed to two electrons) was found to be f{sub {mu}{mu}} = 0.839 {+-} 0.066. The relative branching ratio of the two decays is then calculated based on the equation: BR(B{sup {+-}} {yields} {phi}K{sup {+-}})/BR(B{sup {+-}} {yields} J/{psi}K{sup {+-}}) = N{sub {phi}K}/N{sub {psi}K} {center_dot}f{sub {mu}{mu}} BR(J/{psi} {yields} {mu}{sup +}{mu}{sup -})/BR({phi} {yields} K{sup +}K{sup -}) {epsilon}{sub {mu}{mu}}K/{epsilon}KKK R({epsilon}{sub iso}). The measurement finds BR(B{sup {+-}} {yields} {phi}K{sup {+-}})/BR(B{sup {+-}} {yields} J/{psi}K{sup {+-}}) = 0.0068 {+-} 0.0021(stat.) {+-} 0.0007(syst.). The B{sup {+-}} {yields} {phi}K{sup {+-}} branching ratio is then found to be BR(B{sup {+-}} {yields} {phi}K{sup {+-}}) = [6.9 {+-} 2.1(stat.) {+-} 0.8(syst.)] x 10{sup -6}. This value is consistent with similar measurements reported by the e{sup +}e{sup -} collider experiments BaBar[1], Belle[2], and CLEO[3].

Kinetics and mechanisms of reactions involving small aromatic reactive intermediates  

SciTech Connect (OSTI)

Small aromatic radicals such as C{sub 6}H{sub 5}, C{sub 6}H{sub 5}O and C{sub 6}H{sub 4} are key prototype species of their homologs. C{sub 6}H{sub 5} and its oxidation product, C{sub 6}H{sub 5}O are believed to be important intermediates which play a pivotal role in hydrocarbon combustion, particularly with regard to soot formation. Despite their fundamental importance, experimental data on the reaction mechanisms and reactivities of these species are very limited. For C{sub 6}H{sub 5}, most kinetic data except its reactions with NO and NO{sub 2}, were obtained by relative rate measurements. For C{sub 6}H{sub 5}O, the authors have earlier measured its fragmentation reaction producing C{sub 5}H{sub 5} + CO in shock waves. For C{sub 6}H{sub 4}, the only rate constant measured in the gas phase is its recombination rate at room temperature. The authors have proposed to investigate systematically the kinetics and mechanisms of this important class of molecules using two parallel laser diagnostic techniques--laser resonance absorption (LRA) and resonance enhanced multiphoton ionization mass spectrometry (REMPI/MS). In the past two years, study has been focused on the development of a new multipass adsorption technique--the {open_quotes}cavity-ring-down{close_quotes} technique for kinetic applications. The preliminary results of this study appear to be quite good and the sensitivity of the technique is at least comparable to that of the laser-induced fluorescence method.

Sorption characteristics of polycyclic aromatic hydrocarbons in aluminum smelter residues  

SciTech Connect (OSTI)

High temperature carbon oxidation in primary aluminum smelters results in the release of polycyclic aromatic hydrocarbons (PAH) into the environment. The main source of PAH are the anodes, which are composed of petroleum coke (black carbon, BC) and coal tar pitch. To elucidate the dominant carbonaceous phase controlling the environmental fate of PAH in aluminum smelter residues (coke BC and/or coal tar), the sorptive behavior of PAHs has been determined, using passive samplers and infinite-sink desorption methods. Samples directly from the wet scrubber were studied as well as ones from an adjacent 20-year old storage lagoon and roof dust from the smelter. Carbon-normalized distribution coefficients of native PAHs were 2 orders of magnitude higher than expected based on amorphous organic carbon (AOC)/water partitioning, which is in the same order of magnitude as reported literature values for soots and charcoals. Sorption isotherms of laboratory-spiked deuterated phenanthrene showed strong (about 100 times stronger than AOC) but nonetheless linear sorption in both fresh and aged aluminum smelter residues. The absence of nonlinear behavior typical for adsorption to BC indicates that PAH sorption in aluminum smelter residues is dominated by absorption into the semi-solid coal tar pitch matrix. Desorption experiments using Tenax showed that fresh smelter residues had a relatively large rapidly desorbing fraction of PAH (35-50%), whereas this fraction was strongly reduced (11-16%) in the lagoon and roof dust material. Weathering of the coal tar residue and/or redistribution of PAH between coal tar and BC phases could explain the reduced availability in aged samples. 38 refs., 5 figs., 1 tab.

Measurement of J/psi meson and b-hadron production cross section at sqrt(s) = 1.96 TeV  

SciTech Connect (OSTI)

A new measurement of the inclusive and differential production cross sections of J/{psi} mesons and b-hadrons in proton-antiproton collisions at {radical}s = 1960 GeV is presented. The data correspond to an integrated luminosity of 39.7 pb{sup -1} collected by the CDF Run II detector. The integrated cross section for inclusive J/{psi} production for all transverse momenta from 0 to 20 GeV/c in the rapidity range |y| < 0.6 is found to be 4.08 {+-} 0.02(stat){sub -0.33}{sup +0.36}(syst) {mu}b. The fraction of J/{psi} events from the decay of the long-lived b-hadrons is separated by using the lifetime distribution in all events with p{sub T}(J/{psi}) > 1.25 GeV/c. The total cross section for b-hadrons, including both hadrons and anti-hadrons, decaying to J/{psi} with transverse momenta greater than 1.25 GeV/c in the rapidity range |y(J/{psi})| < 0.6, is found to be 0.330 {+-} 0.005(stat){sub -0.033}{sup +0.036}(syst) {mu}b. Using a Monte Carlo simulation of the decay kinematics of b-hadrons to all final states containing a J/{psi}, the first measurement of the total single b-hadron cross section down to zero transverse momentum is extracted at sqrts = 1960 GeV. The total single b-hadron cross section integrated over all transverse momenta for b-hadrons in the rapidity range |y| < 0.6 is found to be 17.6 {+-} 0.4(stat){sub -2.3}{sup +2.5}(syst) {mu}b.

Max Tech and Beyond: Maximizing Appliance and Equipment Efficiency by Design  

SciTech Connect (OSTI)

It is well established that energy efficiency is most often the lowest cost approach to reducing national energy use and minimizing carbon emissions. National investments in energy efficiency to date have been highly cost-effective. The cumulative impacts (out to 2050) of residential energy efficiency standards are expected to have a benefit-to-cost ratio of 2.71:1. This project examined energy end-uses in the residential, commercial, and in some cases the industrial sectors. The scope is limited to appliances and equipment, and does not include building materials, building envelopes, and system designs. This scope is consistent with the scope of DOE's appliance standards program, although many products considered here are not currently subject to energy efficiency standards. How much energy could the United States save if the most efficient design options currently feasible were adopted universally? What design features could produce those savings? How would the savings from various technologies compare? With an eye toward identifying promising candidates and strategies for potential energy efficiency standards, the Max Tech and Beyond project aims to answer these questions. The analysis attempts to consolidate, in one document, the energy savings potential and design characteristics of best-on-market products, best-engineered products (i.e., hypothetical products produced using best-on-market components and technologies), and emerging technologies in research & development. As defined here, emerging technologies are fundamentally new and are as yet unproven in the market, although laboratory studies and/or emerging niche applications offer persuasive evidence of major energy-savings potential. The term 'max tech' is used to describe both best-engineered and emerging technologies (whichever appears to offer larger savings). Few best-on-market products currently qualify as max tech, since few apply all available best practices and components. The three primary analyses presented in this report are: Nevertheless, it is important to analyze best-on-market products, since data on truly max tech technologies are limited. (1) an analysis of the cross-cutting strategies most promising for reducing appliance and equipment energy use in the U.S.; (2) a macro-analysis of the U.S. energy-saving potential inherent in promising ultra-efficient appliance technologies; and (3) a product-level analysis of the energy-saving potential.

Process for removing halogenated aliphatic and aromatic compounds from petroleum products  

DOE Patents [OSTI]

A process for removing halogenated aliphatic and aromatic compounds, e.g., polychlorinated biphenyls, from petroleum products by solvent extraction. The halogenated aliphatic and aromatic compounds are extracted from a petroleum product into a polar solvent by contacting the petroleum product with the polar solvent. The polar solvent is characterized by a high solubility for the extracted halogenated aliphatic and aromatic compounds, a low solubility for the petroleum product and considerable solvent power for polyhydroxy compound. The preferred polar solvent is dimethylformamide. A miscible compound, such as, water or a polyhydroxy compound, is added to the polar extraction solvent to increase the polarity of the polar extraction solvent. The halogenated aliphatic and aromatic compounds are extracted from the highly-polarized mixture of water or polyhydroxy compound and polar extraction solvent into a low polar or nonpolar solvent by contacting the water or polyhydroxy compound-polar solvent mixture with the low polar or nonpolar solvent. The halogenated aliphatic and aromatic compounds and the low polar or nonpolar solvent are separated by physical means, e.g., vacuum evaporation. The polar and nonpolar solvents are recovered from recycling. The process can easily be designed for continuous operation. Advantages of the process include that the polar solvent and a major portion of the nonpolar solvent can be recycled, the petroleum products are reclaimable and the cost for disposing of waste containing polychlorinated biphenyls is significantly reduced.

Measurement of sigma(chi(c2)B(chi(c2) ---> J / psi gamma) / sigma(chi(c1)B(chi(c1) ---> J / psi gamma) in p anti-p collisions at s**(1/2) = 1.96-TeV

This measurement covers the kinematic range p{sub T} (J/{psi}) > 4.0 GeV/c, |{eta}(J/{psi})| < 1.0, and p{sub T}({gamma}) > 1.0 GeV/c. For events due to prompt processes, they find R{sub p} = 0.395 {+-} 0.016(stat.) {+-} 0.015(sys.).

Study of {psi}(2S) decays to {gamma}pp, {pi}{sup 0}pp, and {eta}pp, and search for pp threshold enhancements  

SciTech Connect (OSTI)

The decays of {psi}(2S) into {gamma}pp, {pi}{sup 0}pp, and {eta}pp have been studied with the CLEO-c detector using a sample of 24.5x10{sup 6} {psi}(2S) events obtained from e{sup +}e{sup -} annihilations at {radical}(s)=3686 MeV. The data show evidence for the excitation of several N{sup *} resonances in p{pi}{sup 0} and p{eta} channels in {pi}{sup 0}pp and {eta}pp decays, and f{sub 2} states in {gamma}pp decay. Branching fractions for decays of {psi}(2S) to {gamma}pp, {pi}{sup 0}pp, and {eta}pp have been determined. No evidence for pp threshold enhancements was found in the reactions {psi}(2S){yields}Xpp, where X={gamma}, {pi}{sup 0}, {eta}. We do, however, find confirming evidence for a pp threshold enhancement in J/{psi}{yields}{gamma}pp as previously reported by BES.

Measurements of time-dependent CP violation in B{sup 0}{yields}{psi}(2S)K{sub S}{sup 0} decays  

SciTech Connect (OSTI)

We report improved measurements of time-dependent CP violation parameters for B{sup 0}(B{sup 0}){yields}{psi}(2S)K{sub S}{sup 0}. This analysis is based on a data sample of 657x10{sup 6} BB pairs collected at the {upsilon}(4S) resonance with the Belle detector at the KEKB energy-asymmetric e{sup +}e{sup -} collider. We fully reconstruct one neutral B meson in the {psi}(2S)K{sub S}{sup 0} CP-eigenstate decay channel, and the flavor of the accompanying B meson is identified to be either B{sup 0} or B{sup 0} from its decay products. CP violation parameters are obtained from the asymmetries in the distributions of the proper-time intervals between the two B decays: S{sub {psi}}{sub (2S)K{sub S{sup 0}}=+0.72{+-}0.09(stat){+-}0.03(syst), A{sub {psi}}{sub (2S)}K{sub S{sup 0}}=+0.04{+-}0.07(stat){+-}0.05(syst).

Evaluation of a new chromatographic method for aromatics in diesel fuels  

SciTech Connect (OSTI)

A new analytical method using supercritical fluid chromatography (SFC) with flame ionization detection (FID) was evaluated for the determination of the aromatics in diesel fuels. The method utilizes high performance liquid chromatography (HPLC) with a packed silica column and supercritical CO/sub 2/ as the carrier fluid. Performance evaluation was carried out using diesel fuels and secondary standards with a wide range of chemical composition. The aromatic content in the fuels was verified by the fluorescent indicator adsorption (FIA) and proton nuclear magnetic resonance (/sup 1/H NMR) methods. With the exception of initial moderate cost of the instrument, the method is simple, fast (less than 20 minutes per sample) and applicable to coloured samples and samples with final boiling points of about 450/sup 0/C. Aromatic concentrations in diesels showed good correlation with FIA data. It is well suited to petroleum refinery applications as an alternate for standard FIA methods.

Effect of microstructure anisotropy on the deformation of MAX polycrystals studied by in-situ compression combined with neutron diffraction  

SciTech Connect (OSTI)

In situ compression tests combined with neutron diffraction were performed on Ti{sub 2}AlN MAX polycrystals with lamellar anisotropic microstructure: the diffraction peak evolution (position and profile) with applied stress reveals that lamellar grains parallel to compression axis remain elastic while lamellar grains perpendicular to compression plastify, both families being subjected to strong variations of heterogeneous strains (types II and III). We demonstrate that this behavior originates from the complex response of the very anisotropic lamellar microstructure and explains the observation of reversible hysteretic loops when cycling MAX polycrystals even in the elastic regime.

Ligand-exchange chromatography of aromatic amines on resin-bound cobalt ion  

SciTech Connect (OSTI)

The use of cobalt metal for the selective separation of aromatic amines is completed with a chemically bonded diamine and glyoxime functional groups onto Lycopodium clavatum. Oximes and amines are excellent complexing agents for transition metal ions. Cobalt(II) metal ions can easily be immobilized on bis-diaminoethyl-glyoximated sporopollenin (bDAEG-sporopollenin). The ligand-exchange behavior of modified Lycopodium clavatum with respect to aromatic amines was investigated. This will permit the evaluation of bDAEG-sporopollenin ligand exchangers for their utilization as sorbents in the recovery, pollution control, and elimination of amines from wastewater.

In this work we investigate the photoproduction of radially excited vector mesons off nuclei in heavy ion relativistic collisions. In particular, we analyze the exclusive photoproduction of psi(2S) off nuclei, evaluating the coherent and the incoherent contributions to that process. The theoretical framework used in the present analysis is the light-cone dipole formalism and predictions are done for PbPb collisions at the CERN-LHC energy of 2.76 TeV. The theoretical uncertainties are analyzed and comparison is also done to the recent ALICE Collaboration data for the psi(1S) state photoproduction.

Boride-based nano-laminates with MAX-phase-like behaviour  

SciTech Connect (OSTI)

MAX-phases being usually composed of transition metals, group A elements and carbon/nitrogen are considered interesting materials for many applications because of their tremendous bulk modulus, 'reversible' plasticity, and machinability. This is mainly due to their unique kind of bonding comprising covalent, ionic as well as metallic bonds providing 'easy' planes of rupture and deformability due to the layered crystal structures. In transition metal boride systems, similar types of bonding are available. In particular the W{sub 2}B{sub 5}-structure type and its stacking variations allow the synthesis of strongly layered crystal structures exhibiting unique delamination phenomena. The paper presents ab initio calculations showing the similarities of bonding between the ternary carbides and the corresponding ternary or quaternary borides. Formation of boride-based nano-laminates from auxiliary liquid phases, from the melt as well as during sintering and precipitation from supersaturated solid solutions will be discussed by means of SEM and TEM studies. The role of impurities weakening the interlayer bonding will be addressed in particular. The pronounced cleavage parallel to the basal plane gives rise for crack deflection and pull-out mechanisms if the laminates are dispersed in brittle matrices such as boron carbide, silicon carbide or other transition metal borides. - Graphical abstract: Some transition metal borides crystallise in a layered structure of alternating stacks of metal and boron atoms giving rise for strongly anisotropic properties. Their preferred cleavage parallel and the deformability perpendicular to the basal plan are similar to the peculiar mechanical behaviour recently described for MAX-phases. Ab initio calculations of the crystal structure prove the weak bonds between the layers for a variety of borides which can be used to reinforce ceramic materials on a nano-scale level.

Aromatic measurements of diesel fuel - A CRC round-robin study  

SciTech Connect (OSTI)

A round robin study to measure the aromatic levels in diesel fuels was conducted by the Chemical Characterization Panel of the Coordinating Research Council Air Pollution Research Advisory Committee (CRC-APRAC) In-house Program Group, CAPI-1-64. The fuels for this study consisted of a jet fuel, a No. 2 diesel reference fuel, and three fuels used in a CRC-sponsored diesel emission project (CAPE-32). These fuels had 90% distillation temperatures which ranged from 472/sup 0/ to 642/sup 0/ F and aromaticity levels from approximately 18 to 55% by volume. All participants used the American Society for Testing and Materials (ASTM) D1319 or modified D1319 methods to measure the aromatic levels in the selected fuels. Some participants concurrently analyzed the same fuels using other methods such as high-performance liquid chromatography, mass spectrometry, nuclear magnetic resonance spectrometry, and elution chromatography (ASTM D2549). One non-participating laboratory analyzed the fuels using supercritical fluid chromatography. The results of nine participants using the D1319 methodology and other methods showed good agreement for fuels with 90% distillation temperatures less than 600/sup 0/ F. However, this round robin study showed that: 1) there is no standard method to measure aromatic levels in full boiling range diesel fuels, and 2) there are inadequacies when using the D1319 and modified D1319 methods for fuels outside of the specified property ranges.

A new carbon-13 method for determining aromatic, naphthenic and paraffinic carbon  

SciTech Connect (OSTI)

The determination of the relative percentages of aromatic, naphthenic and paraffinic carbon in samples of natural origin is important for many petroleum related studies including processing, geological studies, and certain product specifications. The normal method is the n-d-M method which requires the measurement of refractive index, density and molecular weight and a ternary correlation diagram to obtain the relative carbon percentages. It is difficult or inconvenient to make n-d-M measurements of very heavy products and the presence of significant amounts of polar materials makes n-d-M results inaccurate. The average molecular parameters determinable by a number of NMR techniques are directly or indirectly related to the percentage of various carbon types present in the mixture. Unfortunately, all the standard techniques we have examined have some built-in assumption which does not allow the accurate calculation of relative carbon percentages. For example, any proton technique applicable to aromatic fractions will give potentially low values for naphthenic carbon because naphthenic carbon is normally determined from the ..beta..-CH/sub 2/ region of tetralin-type structures (1.65-1.9 ppm). This is a very specific kind of naphthenic structure and to the extent that more than one saturate ring is asymmetrically condensed to the aromatic ring or that the saturate rings are not directly condensed to the aromatic rings, the method will fail.

Kinetics of hydrogenation of aromatics determined by carbon-13 NMR for Athabasca bitumen-derived middle distillates  

SciTech Connect (OSTI)

High aromatics content in middle distillates is detrimental to fuel quality, as shown in such properties as smoke point of jet fuel and cetane number of diesel fuel. In the petroleum and petrochemical industries the yields from fluid catalytic cracking or steam cracking units are adversely affected by high aromatics content in the feedstock. Distillates obtained from oil sand bitumen, heavy oils, or coal liquefaction products are particularly high in aromatics. Reducing the concentration of this class of compounds is important. Aromatics hydrogenation (AHYD) is one option to achieve this result. In the current Syncrude operation a primary objective of hydrotreating is to reduce product sulfur and nitrogen contents; reducing aromatics content is an incidental result. However, the expansion plan currently under study by Syncrude includes further AHYD to improve cetane number. Predicting the product aromatics content is an important issue for this study. In the present study, hydrotreating of five Athabasca-bitumen-derived gas oils was conducted in pilot scale trickle-bed reactors using alumina-based commercial NiMo catalysts. Feedstocks originated from the distillation of virgin bitumen, and from distillates derived from treating bitumen in a fluid coker and hydrocracking pilot plant. Aromatics content was determined by the {sup 13}C NMR method. The previously developed rate equation for AHYD was modified by including power terms for space velocity and hydrogen partial pressure. The data were analyzed using the modified equation.

Cold nuclear matter effects on the color singlet J/psi production in d-Au collisions at RHIC  

E-Print Network [OSTI]

We use a Modified DKLMT model (called M-DKLMT model) to study the cold nuclear matter (CNM) effects on the color singlet J/psi production in dAu collisions at RHIC. The cold nuclear effect of dipole-nucleus interactions has been investigated by introducing a nuclear geometric effect function f({\\xi}) to study the nuclear geometry distribution effect in relativistic heavy-ion collisions. The dependencies of nuclear modification factors (RdA) on rapidity and centrality are studied and compared to experimental data. It is found that the M-DKLMT model can well describe the experimental results at both forward- and mid-rapidity regions in dAu collisions at RHIC.

The alkyl, naphthenic, or total carbon atoms of the functional groups at alpha position to aromatic rings and their hydrogen to carbon ratio are some of the important parameters for structural analysis of fossil fuel products. In this paper, the authors present a number of novel formula-structure relationships for precise determination of different carbon atom types at alpha position to aromatic rings and the average number of hydrogens per alpha-carbon.

Catalytic oxidation of 2-aminophenols and ortho hydroxylation of aromatic amines by tyrosinase  

SciTech Connect (OSTI)

The usual substrates of tyrosinase, a copper-containing monooxygenase (EC 1.14.18.1), are monophenols and o-diphenols which are both converted to o-quinones. In this paper, the authors studied the reaction of this enzyme with two new classes of substrates: aromatic amines and o-aminophenols, structural analogues of monophenols and o-diphenols, respectively. They undergo the same catalytic reactions (ortho hydroxylation and oxidation), as documented by product analysis and kinetic studies. In the presence of tyrosinase, arylamines and o-aminophenols are converted to o-quinone imines, which are isolated as quinone anils or phenoxazones. As an example, in the presence of tyrosinase, 2-amino-3-hydroxybenzoic acid (an o-aminophenol) is converted to cinnabarinic acid, a well-known phenoxazone, while p-aminotoluene (an aromatic amine) gives rise to the formation of 5-amino-2-methyl-1,4-benzoquinone 1-(4-methylanil). Kinetic studies using an oxygen electrode show that arylamines and the corresponding monophenols exhibit similar Michaelis constants. In contrast, the reaction rates observed for aromatic amines are relatively slow as compared to monophenols. The enzymatic conversion of arylamines by tryosinase is different from the typical ones: N-oxidation and ring hydroxylation without further oxidation. This difference originates from the regiospecific hydroxylation (ortho position) and subsequent oxidation of the intermediate o-aminophenol to the corresponding o-quinone imine. Finally, the well-know monooxygenase activity of tyrosinase was also confirmed for the aromatic amine p-aminotoluene, with /sup 18/O/sub 2/.

Handling Radioactive Waste from the Proton Accelerator Facility at the Paul Scherrer Institut (PSI) - Always Surprising? - 13320  

SciTech Connect (OSTI)

The Paul Scherrer Institut (PSI) is the largest national research centre in Switzerland. Its multidisciplinary research is dedicated to a wide field in natural science and technology as well as particle physics. In this context, PSI is operating, amongst others, a large proton accelerator facility since more than 30 years. In two cyclotrons, protons are accelerated to high speeds and then guided along roughly 100 m of beam line to three different target stations to produce secondary particles like mesons and neutrons for experiments and a separately beam line for UCN. The protons induce spallation processes in the target materials, and also at other beam loss points along the way, with emission of protons, neutrons, hydrogen, tritium, helium, heavier fragments and fission processes. In particular the produced neutrons, due to their large penetration depth, will then interact also with the surrounding materials. These interactions of radiation with matter lead to activation and partly to contamination of machine components and the surrounding infrastructures. Maintenance, operation and decommissioning of installations generate inevitably substantial amounts of radioactive operational and dismantling waste like targets, magnets, collimators, shielding (concrete, steel) and of course secondary waste. To achieve an optimal waste management strategy for interim storage or final disposal, radioactive waste has to be characterized, sorted and treated. This strategy is based on radiation protection demands, raw waste properties (size, material, etc.), and requirements to reduce the volume of waste, mainly for legal and economical reasons. In addition, the radiological limitations for transportation of the waste packages to a future disposal site have to be taken into account, as well as special regulatory demands. The characterization is a task of the waste producer. The conditioning processes and quality checks for radioactive waste packages are part of an accredited waste management process of PSI, especially of the Section Dismantling and Waste Management. Strictly proven and accepted methods needed to be developed and enhanced for safe treatment, transport, conditioning and storage. But in the field of waste from research activities, individual and new solutions have to be found in an increasingly growing administrative environment. Furthermore, a wide variety of components, with a really large inventory of radioactive nuclides, has to be handled. And there are always surprising challenges concerning the unusual materials or the nuclide inventory. In case of the operational and dismantling radioactive accelerator waste, the existing conditioning methods are in the process of a continuous enhancement - technically and administratively. The existing authorized specifications of conditioning processes have to be extended to optimize and fully describe the treatment of the inevitably occurring radioactive waste from the accelerator facility. Additional challenges are the changes with time concerning the legal and regulatory requirements - or do we have to consider it as business as usual? This paper gives an overview of the current practices in radioactive waste management and decommissioning of the existing operational accelerator waste. (authors)

With a sample of (225.2{+-}2.8)x10{sup 6} J/{psi} events registered in the BESIII detector, J/{psi}{yields}{gamma}{pi}{sup +}{pi}{sup -}{eta}' is studied using two {eta}{sup '} decay modes: {eta}{sup '}{yields}{pi}{sup +}{pi}{sup -}{eta} and {eta}{sup '}{yields}{gamma}{rho}{sup 0}. The X(1835), which was previously observed by BESII, is confirmed with a statistical significance that is larger than 20{sigma}. In addition, in the {pi}{sup +}{pi}{sup -}{eta}' invariant-mass spectrum, the X(2120) and the X(2370), are observed with statistical significances larger than 7.2{sigma} and 6.4{sigma}, respectively. For the X(1835), the angular distribution of the radiative photon is consistent with expectations for a pseudoscalar.

Eclipsing binaries observed with the WIRE satellite I. Discovery and photometric analysis of the new bright A0IV eclipsing binary Psi Centauri  

E-Print Network [OSTI]

Determinations of stellar mass and radius with realistic uncertainties at the level of 1% provide important constraints on models of stellar structure and evolution. We present a high-precision light curve of the A0IV star Psi Centauri, from the star tracker on board the WIRE satellite and the Solar Mass Ejection Imager camera on the Coriolis spacecraft. The data show that Psi Cen is an eccentric eclipsing binary system with a relatively long orbital period. The WIRE light curve extends over 28.7 nights and contains 41334 observations with 2 mmag point-to-point scatter. The eclipse depths are 0.28 and 0.16 mag, and show that the two eclipsing components of Psi Cen have very different radii. As a consequence, the secondary eclipse is total. We find the eccentricity to be e=0.55 with an orbital period of 38.8 days from combining the WIRE light curve with data taken over two years from the Solar Mass Ejection Imager camera. We have fitted the light curve with EBOP and have assessed the uncertainties of the resulting parameters using Monte Carlo simulations. The fractional radii of the stars and the inclination of the orbit have random errors of only 0.1% and 0.01 degrees, respectively, but the systematic uncertainty in these quantities may be somewhat larger. We have used photometric calibrations to estimate the effective temperatures of the components of Psi Cen to be 10450+-300 and 8800+-300 K, indicating masses of about 3.1 and 2.0 Msun. There is evidence in the WIRE light curve for g-mode pulsations in the primary star.

Process for removing halogenated aliphatic and aromatic compounds from petroleum products. [Polychlorinated biphenyls; methylene chloride; perchloroethylene; trichlorofluoroethane; trichloroethylene; chlorobenzene  

DOE Patents [OSTI]

A process for removing halogenated aliphatic and aromatic compounds, e.g., polychlorinated biphenyls, from petroleum products by solvent extraction. The halogenated aliphatic and aromatic compounds are extracted from a petroleum product into a polar solvent by contracting the petroleum product with the polar solvent. The polar solvent is characterized by a high solubility for the extracted halogenated aliphatic and aromatic compounds, a low solubility for the petroleum product and considerable solvent power for polyhydroxy compound. The preferred polar solvent is dimethylformamide. A miscible polyhydroxy compound, such as, water, is added to the polar extraction solvent to increase the polarity of the polar extraction solvent. The halogenated aliphatic and aromatic compounds are extracted from the highly-polarized mixture of polyhydroxy compound and polar extraction solvent into a low polar or nonpolar solvent by contacting the polyhydroxy compound-polar solvent mixture with the low polar or nonpolar solvent. The halogenated aliphatic and aromatic compounds in the low polar or nonpolar solvent by physical means, e.g., vacuum evaporation. The polar and nonpolar solvents are recovered for recycling. The process can easily be designed for continuous operation. Advantages of the process include that the polar solvent and a major portion of the nonpolar solvent can be recycled, the petroleum products are reclaimable and the cost for disposing of waste containing polychlorinated biphenyls is significantly reduced. 2 tables.

1D-8 Duo-Binary Circular Turbo Decoder Based on Border Metric Encoding for WiMAX  

E-Print Network [OSTI]

Abstract- This paper presents a duo-binary circular turbo decoder based on border metric encoding. With the proposed method, the memory size for branch memory is reduced by half and the dummy calculation is removed at the cost of the small-sized memory which holds the encoded border metrics. Based on the proposed SISO decoder and the dedicated hardware interleaver, a duo-binary circular turbo decoder is designed for the WiMAX standard using a 0.13 ?m CMOS process, which can support 24.26 Mbps at 200MHz.

Reconciling the light-cone and nonrelativistic QCD approaches to calculating e+ e- -> J/psi + eta_c  

E-Print Network [OSTI]

It has been suggested in Ref. [A. E. Bondar and V. L. Chernyak, Phys. Lett. B 612, 215 (2005)] that the disagreement between theoretical calculations and experimental observations for the rate for the process e+ e- -> J/psi + eta_c at the B factories might be resolved by using the light-cone method to take into account the relative momentum of the heavy-quark and antiquark in the quarkonia. The light-cone result for the production cross section in Ref. [A. E. Bondar and V. L. Chernyak, Phys. Lett. B 612, 215 (2005)] is almost an order of magnitude larger than existing NRQCD factorization results. We investigate this apparent theoretical discrepancy. We compute light-cone distribution functions by making use of quarkonium wave functions from the Cornell potential model. Our light-cone distribution functions are similar in shape to those of Ref. [A. E. Bondar and V. L. Chernyak, Phys. Lett. B 612, 215 (2005)] and yield a similar cross section. However, when we subtract parts of the light-cone distribution functions that correspond to corrections of relative-order alpha_s in the NRQCD approach, we find that the cross section decreases by about a factor of three. When we set certain renormalization factors Z_i in the light-cone calculation equal to unity, we find a further reduction in the cross section of about a factor of two. The resulting light-cone cross section is similar in magnitude to the NRQCD factorization cross sections and shows only a modest enhancement over the light-cone cross section in which the relative momentum of the heavy-quark and antiquark is neglected.

Using 535x10{sup 6} B-meson pairs collected by the Belle detector at the KEKB e{sup +}e{sup -} collider, we measure branching fractions of (7.16{+-}0.10(stat){+-}0.60(syst)x10{sup -4} for B{sup +}{yields}J/{psi}K{sup +}{pi}{sup +}{pi}{sup -} and (4.31{+-}0.20(stat){+-}0.50(syst))x10{sup -4} for B{sup +}{yields}{psi}'K{sup +}{pi}{sup +}{pi}{sup -}. We perform amplitude analyses to determine the resonant structure of the K{sup +}{pi}{sup +}{pi}{sup -} final state in B{sup +}{yields}J/{psi}K{sup +}{pi}{sup +}{pi}{sup -} and B{sup +}{yields}{psi}'K{sup +}{pi}{sup +}{pi}{sup -} and find that the K{sub 1}(1270) is a prominent component of both decay modes. There is significant interference among the different intermediate states, which leads, in particular, to a striking distortion of the {rho} line shape due to the {omega}. Based on the results of the fit to the B{sup +}{yields}J/{psi}K{sup +}{pi}{sup +}{pi}{sup -} data, the relative decay fractions of the K{sub 1}(1270) to K{rho}, K{omega}, and K*(892){pi} are consistent with previous measurements, but the decay fraction to K{sub 0}*(1430) is significantly smaller. Finally, by floating the mass and width of the K{sub 1}(1270) in an additional fit of the B{sup +}{yields}J/{psi}K{sup +}{pi}{sup +}{pi}{sup -} data, we measure a mass of (1248.1{+-}3.3(stat){+-}1.4(syst)) MeV/c{sup 2} and a width of (119.5{+-}5.2(stat){+-}6.7(syst)) MeV/c{sup 2} for the K{sub 1}(1270).

Muon capture at PSI  

E-Print Network [OSTI]

Measuring the rate of muon capture in hydrogen provides one of the most direct ways to study the axial current of the nucleon. The MuCap experiment uses a negative muon beam stopped in a time projection chamber operated with ultra-pure hydrogen gas. Surrounded by a decay electron detector, the lifetime of muons in hydrogen can be measured to determine the singlet capture rate Lambda_s to a final precision of 1%. The capture rate determines the nucleon's pseudoscalar form factor g_p. A first result, g_p = 7.3 +- 1.1, has been published and the final analysis of the full statistics will reduce the error by a factor of up to 3. Muon capture on the deuteron probes the weak axial current in the two-nucleon system. Within the framework of effective field theories the calculation of such two-nucleon processes involving the axial current requires the knowledge of one additional low energy constant which can be extracted from the doublet capture rate Lambda_d. The same constant then allows to model-independently calculate related processes such as solar pp-fusion or neutrino-deuteron scattering. The MuSun experiment will deduce Lambda_d to better than 1.5%. The experiment uses the MuCap detection setup with a new time projection chamber operated with deuterium at 30K and several hardware upgrades. The system is currently fully commissioned and the main physics data taking will start in 2011.

MHUG process for production of low sulfur and low aromatic diesel fuel. [Medium-pressure Hydro UpGrading  

SciTech Connect (OSTI)

A new hydro-upgrading process operated under medium pressure has been developed to reduce the sulfur and the aromatics content in light cycle oil (LCO). Two catalysts were used in series in this technology. The commercial RN-1 catalyst, which is known as having high activity in hydrodenitrogenation, desulfurization and aromatic saturation, was chosen as the first catalyst. The second one was a nickel-tungsten zeolite catalyst, named RT-5, which was developed by RIPP specially for hydrogenolysis of naphthenic and aromatic hydrocarbons. The pilot plant tests showed that high quality diesel oil with aromatics content less than 20 v% and sulfur content less than 0.05 wt% could be produced from various LCO/straight-run-gas-oil (SRGO) blended feedstocks under hydrogen partial pressure of 6.4 MPa. The reaction temperature and overall space velocity (S.V.) varied in the range of 350--380 C and 0.6--1.2 h[sup [minus]1], respectively, depending on the properties of the feedstocks to be processed and the upgrading depth required. Several examples presented also illustrated that this technology could be used to prepare catalytic reforming feedstock as well, which is in urgent need in China. A life test operated in relatively high severity for 3,000 hr. indicated that the catalysts possessed excellent stability. A commercial demonstration unit has been running well since the last Oct 1.

Anisotropy and Size Effects on the Optical Spectra of Polycyclic Aromatic Hydrocarbons  

E-Print Network [OSTI]

The electronic and optical properties of polycyclic aromatic hydrocarbons (PAHs) present a strong dependence on their size and geometry. We tackle this issue by analyzing the spectral features of two prototypical classes of PAHs, belonging to D6h and D2h symmetry point groups and related to coronene as multifunctional seed. While the size variation induces an overall red shift of the spectra and a redistribution of the oscillator strength between the main peaks, a lower molecular symmetry is responsible for the appearance of new optical features. Along with broken molecular orbital degeneracies, optical peaks split and dark states are activated in the low-energy part of the spectrum. Supported by a systematic analysis of the composition and the character of the optical transitions, our results contribute in shedding light to the mechanisms responsible for spectral modifications in the visible and near UV absorption bands of medium-size PAHs.

One-electron oxidation in the degradation of creosote polycyclic aromatic hydrocarbons by Phanerochaete chrysoporium  

SciTech Connect (OSTI)

The abilities of whole cultures of Phanerochaete chrysosporium and P. chrysosporium manganese peroxidase-mediated lipid peroxidation reactions to degrade the polycyclic aromatic hydrocarbons (PAHs) found in creosote were studied. The disappearance of 12 three- to six-ring PAHs occurred in both systems. Both in vivo and in vitro, the disappearance of all PAHs was found to be very strongly correlated with ionization potential. This was true even for compounds beyond the ionization potential thresholds of lignin peroxidase and Mn{sup 3+}. Deviations from this correlation were seen in the cases of PAHs which are susceptible to radical addition reactions. These results thus begin to clarify the mechanisms of non-lignin peroxidase-labile PAH degradation in the manganese peroxidase-lipid peroxidation system and provide further evidence for the ability of this system to explain the in vivo oxidation of these compounds. 35 refs., 5 figs., 2 tabs.

THE INFRARED SPECTRA OF POLYCYCLIC AROMATIC HYDROCARBONS WITH SOME OR ALL HYDROGEN ATOMS REMOVED  

SciTech Connect (OSTI)

The loss of one hydrogen from C{sub 96}H{sub 24} does not significantly affect the infrared spectra of the neutral, cation, or anion. Excluding a very weak C-C stretching band at 5.1 ?m, the loss of two adjacent duo hydrogens does not significantly affect the spectra compared with the parent. Removing all of the hydrogen atoms significantly increases the intensity of the new C-C stretching band, and, for the cation, shifts it to a longer (5.2 ?m) wavelength. Observations show a feature near 5.25 ?m, which has been attributed to overtone and combination bands from polycyclic aromatic hydrocarbons (PAHs). This current work suggests that dehydrogenated PAHs might also contribute to this band, but its weakness implies that fully dehydrogenated cationic or dicationic species are very rare.

Rendering graphene supports hydrophilic with non-covalent aromatic functionalization for transmission electron microscopy  

SciTech Connect (OSTI)

Amorphous carbon films have been routinely used to enhance the preparation of frozen-hydrated samples for transmission electron microscopy (TEM), either in retaining protein concentration, providing mechanical stability or dissipating sample charge. However, strong background signal from the amorphous carbon support obstructs that of the sample, and the insulating properties of thin amorphous carbon films preclude any efficiency in dispersing charge. Graphene addresses the limitations of amorphous carbon. Graphene is a crystalline material with virtually no phase or amplitude contrast and unparalleled, high electrical carrier mobility. However, the hydrophobic properties of graphene have prevented its routine application in Cryo-TEM. This Letter reports a method for rendering graphene TEM supports hydrophilica convenient approach maintaining graphene's structural and electrical properties based on non-covalent, aromatic functionalization.

Search for Invisible Decays of {eta} and {eta}{sup '} in J/{psi}{yields}{phi}{eta} and {phi}{eta}{sup '}  

SciTech Connect (OSTI)

Using a data sample of 58x10{sup 6} J/{psi} decays collected with the Beijing Spectrometer II detector at the Beijing Electron Positron Collider, searches for invisible decays of {eta} and {eta}{sup '} in J/{psi} to {phi}{eta} and {phi}{eta}{sup '} are performed. The {phi} signals, which are reconstructed in K{sup +}K{sup -} final states, are used to tag the {eta} and {eta}{sup '} decays. No signals are found for the invisible decays of either {eta} or {eta}{sup '}, and upper limits at the 90% confidence level are determined to be 1.65x10{sup -3} for the ratio (B({eta}{yields}invisible)/B({eta}{yields}{gamma}{gamma})) and 6.69x10{sup -2} for (B({eta}{sup '}{yields}invisible)/B({eta}{sup '}{yields}{gamma}{gamma})).

A study of B(s)0 to J/psi phi in the D0 experiment and an example of HEP technology transfer  

SciTech Connect (OSTI)

After years of preparation, data taking with the upgraded D0 detector at the Tevatron proton-antiproton collider has begun. The large amount of data produced in a p{bar p}-collider requires sophisticated triggers to filter out the interesting events. Described in this thesis is the development of trigger software for the newly implemented Silicon Microstrip Tracker. D0 is a multi-purpose detector with a broad physics program. one area being studied at D0 is B mesons. An algorithm for reconstructing the B{sub s}{sup 0} and B{sub d}{sup 0} mesons and for measuring their lifetimes has been developed and is described in this thesis. The results suggest that an improvement of the current lifetime measurements can be achieved within the next two years. The reconstruction of a J/{psi} meson forms the basis for a wide range of b-physics. Data taken with the muon system during the commissioning period of the detector has been analyzed and a signal for the J/{psi} meson has been found. Systematic transfer of HEP technologies into other areas and their commercial exploitation plays an important role in the future of particle physics. An area of particular interest is DNA sequencing as shown by the recent completion of the sequencing of the human genome. The final part of this thesis details the development of a simulation for a high throughput sequencing device which is currently being developed at Imperial College.

The Mean and Scatter of the Velocity Dispersion-Optical Richness Relation for MaxBCG Galaxy Clusters  

SciTech Connect (OSTI)

The distribution of galaxies in position and velocity around the centers of galaxy clusters encodes important information about cluster mass and structure. Using the maxBCG galaxy cluster catalog identified from imaging data obtained in the Sloan Digital Sky Survey, we study the BCG--galaxy velocity correlation function. By modeling its non-Gaussianity, we measure the mean and scatter in velocity dispersion at fixed richness. The mean velocity dispersion increases from 202 {+-} 10 km s{sup -1} for small groups to more than 854 {+-} 102 km s{sup -1} for large clusters. We show the scatter to be at most 40.5{+-}3.5%, declining to 14.9{+-}9.4% in the richest bins. We test our methods in the C4 cluster catalog, a spectroscopic cluster catalog produced from the Sloan Digital Sky Survey DR2 spectroscopic sample, and in mock galaxy catalogs constructed from N-body simulations. Our methods are robust, measuring the scatter to well within one-sigma of the true value, and the mean to within 10%, in the mock catalogs. By convolving the scatter in velocity dispersion at fixed richness with the observed richness space density function, we measure the velocity dispersion function of the maxBCG galaxy clusters. Although velocity dispersion and richness do not form a true mass--observable relation, the relationship between velocity dispersion and mass is theoretically well characterized and has low scatter. Thus our results provide a key link between theory and observations up to the velocity bias between dark matter and galaxies.

Two-stage hydrotreating of a bitumen-derived middle distillate to produce diesel and jet fuels, and kinetics of aromatics hydrogenation  

SciTech Connect (OSTI)

The middle distillate from a synthetic crude oil derived from Athabasca bitumen was further hydrotreated in a downflow pilot unit over a typical NiMo catalyst at 330 to 400 C, 7 to 11 MPa and 0.63 to 1.39 h{sup {minus}1} LHSV. Feed and liquid products were characterized for aromatics, cetane index (CI) and other diesel specification items. Aromatics were determined by a supercritical fluid chromatography method, while CI was determined using the correlation developed at Syncrude Canada Ltd. Also feed and selected products were distilled into a jet fuel cut (150/260 C) by spinning band distillation for the determination of smoke point and other jet fuel specification items. A good relationship between aromatics content and CI was obtained. Kinetics of aromatics hydrogenation were investigated, employing a simple-first order reversible reaction model.

The unusual hydrocarbon emission from the early carbon star HD 100764: The connection between aromatics and aliphatics  

E-Print Network [OSTI]

We have used the Infrared Spectrograph (IRS) on the Spitzer Space Telescope to obtain spectra of HD 100764, an apparently single carbon star with a circumstellar disk. The spectrum shows emission features from polycyclic aromatic hydrocarbons (PAHs) that are shifted to longer wavelengths than normally seen, as characteristic of ``class C'' systems in the classification scheme of Peeters et al. All seven of the known class C PAH sources are illuminated by radiation fields that are cooler than those which typically excite PAH emission features. The observed wavelength shifts are consistent with hydrocarbon mixtures containing both aromatic and aliphatic bonds. We propose that the class C PAH spectra are distinctive because the carbonaceous material has not been subjected to a strong ultraviolet radiation field, allowing relatively fragile aliphatic materials to survive.

Measurement of the parity-violating asymmetry parameter alpha_b and the helicity amplitudes for the decay Lambda_b->J/psi+Lambda with the ATLAS detector  

E-Print Network [OSTI]

A measurement of the parity-violating decay asymmetry parameter, alpha_b, and the helicity amplitudes for the decay Lambda_b->J/psi(mu mu)+Lambda(p pi) is reported. The analysis is based on 1400 Lambda_b and anti-Lambda_b baryons selected in 4.6/fb of proton-proton collision data with a center-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. By combining the Lambda_b and anti-Lambda_b samples under the assumption of CP conservation, the value of alpha_b is measured to be 0.30+/-0.16(stat)+/-0.06(syst). This measurement provides a test of theoretical models based on perturbative QCD or heavy-quark effective theory.

Study of {Lambda}-{Lambda} oscillation in quantum coherent {Lambda}{Lambda} by using J/{psi}{yields}{Lambda}{Lambda} decay  

SciTech Connect (OSTI)

We discuss the possibility of searching for the {Lambda}-{Lambda} oscillations for coherent {Lambda}{Lambda} production in the J/{psi}{yields}{Lambda}{Lambda} decay process. The sensitivity of measurement of {Lambda}-{Lambda} oscillation in the external field at BES-III experiment is considered. These considerations indicate an alternative way to probe the {Delta}B=2 amplitude in addition to neutron oscillation experiments. Both coherent and time-dependent information can be used to extract the {Lambda}-{Lambda} oscillation parameter. With one year's luminosity at BES-III, we can set an upper limit of {delta}m{sub {Lambda}{Lambda}<}10{sup -15} MeV at 90% confidence level, corresponding to about 10{sup -6} s of {Lambda}-{Lambda} oscillation time.

Removal of phenols and aromatic amines from wastewater by a combination treatment with tyrosinase and a coagulant  

SciTech Connect (OSTI)

Removal of phenols and aromatic amines from industrial wastewater by tyrosinase was investigated. A color change from colorless to dark brown was observed, but no precipitate was formed. Colored products were found to be easily removed by a combination treatment with tyrosinase and a cationic polymer coagulant containing amino group, such as hexamethylenediamine-epichlorohidrin polycondensate, polyethleneimine, or chitosan. The first two coagulants, synthetic polymers, were more effective than chitosan, a polymer produced in crustacean shells. Phenols and aromatic amines are not precipitated by any kind of coagulants, but their enzymatic reaction products are easily precipitated by a cationic polymer coagulant. These results indicate that the combination of tyrosinase and a cationic polymer coagulant is effective in removing carcinogenic phenols and aromatic amines from an aqueous solution. Immobilization of tyrosinase on magnetite gave a good retention of activity (80%) and storage stability i.e., only 5% loss after 15 days of storage at ambient temperature. In the treatment of immobilized tyrosinase, colored enzymatic reaction products were removed by less coagulant compared with soluble tyrosinase.

The importance of snow scavenging of polychlorinated biphenyl and polycyclic aromatic hydrocarbon vapors  

SciTech Connect (OSTI)

Recently, experimental data on the scavenging of polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) from the atmosphere by snow were interpreted assuming that the distribution of chemical between particles and dissolved phase measured in the meltwater reflects the state of the chemical during the scavenging process. A consequence of this assumption is that vapor scavenging is found to be unimportant relative to particle scavenging. An alternative interpretation is presented that during melting repartitioning occurs from the dissolved phase to the particle-sorbed phase. Further, it is argued that a constant particle scavenging ratio may apply to all chemicals of the same class in the same precipitation event, and its value can be estimated from the scavenging characteristics of predominantly particle-sorbed, high molecular mass chemicals. This analysis suggests that for more volatile PCBs and PAHs vapor scavenging is an important, if not the dominating, snow scavenging process. Gas scavenging ratios obtained with this method are, as expected, negatively correlated with the vapor pressure of a substance, indicating that adsorption to the air-ice interface is the process responsible for vapor scavenging.

Hydrogenation of aromatics in synthetic crude distillates catalyzed by platinum supported in molecular sieves  

SciTech Connect (OSTI)

Catalytic hydrogenation of synthetic crude distillates from Canadian oil sands was carried out over platinum metal supported in pillared interlayered clay (PILC) and Y-zeolite. The molecular sieve supports were employed to modify the properties of dispersed platinum particles and improve their resistance to poisoning by sulfur. The objective was to reduce the distillate aromatic content to meet diesel emission control standards and cetane number requirements. Catalysts were prepared in a series of steps, and metal precursor was loaded using ion-exchange procedures. Characterization was done using X-ray diffraction, hydrogen chemisorption, and proton-induced X-ray emission elemental analysis. Catalytic hydrogenation reactions were carried out by processing distillate feedstocks both high (>100 ppm) and low (<10 ppm) in sulfur using a continuous-flow automated microreactor system. Experimental runs were performed to determine the reaction kinetics and Arrhenius parameters as a means of evaluating and comparing catalyst performance. Significant differences in catalyst activity were found. The Pt/Y-zeolite-alumina catalyst showed a much superior hydrogenation performance under conditions of high sulfur content. The extent of cracking and ring opening was also evaluated and was shown to be minimal under the operating conditions employed.

Measurement of polynuclear aromatic hydrocarbon concentrations in the plume of Kuwait oil well fires  

SciTech Connect (OSTI)

Following their retreat from Kuwait during February and March of 1991, the Iraqi Army set fire to over 500 oil wells dispersed throughout the Kuwait oil fields. During the period of sampling from July to August 1991, it was estimated that between 3.29 {times} 10{sup 6} barrels per day of crude oil were combusted. The resulting fires produced several plumes of black and white smoke that coalesced to form a composite ``super`` plume. Because these fires were uncontrolled, significant quantities of organic materials were dispersed into the atmosphere and drifted throughout the Middle East. The organic particulants associated with the plume of the oil well fires had a potential to be rich in polynuclear aromatic hydrocarbon (PAH) compounds. Based on the extreme mutagenic and carcinogenic activities of PAHs found in laboratory testing, a serious health threat to the population of that region potentially existed. Furthermore, the Kuwait oil fire plumes represented a unique opportunity to study the atmospheric chemistry associated with PAHs in the plume. If samples were collected near the plume source and from the plume many kilometers downwind from the source, comparisons could be made to better understand atmospheric reactions associated with particle-bound and gas-phase PAHs. To help answer health-related concerns and to better understand the fate and transport of PAHs in an atmospheric environment, a sampling and analysis program was developed.

In this paper, we have designed four diphenylaminofluorenylstyrene derivatives end-capped with heterocyclic aromatic groups, such as 9-phenylcabazole, 4-dibenzofuran, 2-benzoxazole, 2-quinoxaline, respectively. These materials showed blue to red fluorescence with maximum emission wavelengths of 476611 nm, respectively, which were dependent on the structural and electronic nature of end-capping groups. To explore the electroluminescent properties of these materials, multilayer OLEDs were fabricated in the following sequence: ITO/DNTPD (40 nm)/NPB (20 nm)/2% doped in MADN (20 nm)/Alq{sub 3} (40 nm)/Liq.

Polycyclic aromatic hydrocarbon contamination in marine sediments near Kitimat, British Columbia  

SciTech Connect (OSTI)

Polycyclic aromatic hydrocarbons (PAHs), like many other hydrophobic organic contaminants, are rapidly sorbed to particles and incorporated within sediments in aquatic systems. The PAH composition within the sediments reflects the source(s) from which the PAHs were derived. However, the ``source signature`` may be altered by postdepositional weathering or biodegradation. In the present study, variation in PAH composition was investigated in size-fractionated sediments and depth-fractionated sediments collected from a Canadian fjord contaminated with aluminum smelter derived PAHs. Multivariate analyses of PAH compositional data consistently showed that different sampling sites could be discriminated on the basis of their PAH composition, but smaller versus larger size fractions within a site could not. The composition of unsubstituted and alkyl-substituted PAHs in a sediment core primarily showed changes with depth that were attributable to enhancement of anthropogenic inputs in the upper core segments. No trends with sediment depth, associated with compound-specific weathering or biotransformation, were noted in the composition of anthropogenically generated PAHs. This may indicate a limited chemical and biological availability of the aluminum smelter derived PAHs.

Field application of a genetically engineered microorganism for polycyclic aromatic hydrocarbon bioremediation process monitoring and control  

SciTech Connect (OSTI)

On October 30, 1996, the US Environmental Protection Agency (EPA) commenced the first test release of genetically engineered microorganisms (GEMs) for use in bioremediation. The specific objectives of the investigation were multifaceted and include (1) testing the hypothesis that a GEM can be successfully introduced and maintained in a bioremediation process, (2) testing the concept of using, at the field scale, reporter organisms for direct bioremediation process monitoring and control, and (3) acquiring data that can be used in risk assessment decision making and protocol development for future field release applications of GEMs. The genetically engineered strain under investigation is Pseudomonas fluorescens strain HK44 (King et al., 1990). The original P. fluorescens parent strain was isolated from polycyclic aromatic hydrocarbon (PAH) contaminated manufactured gas plant soil. Thus, this bacterium is able to biodegrade naphthalene (as well as other substituted naphthalenes and other PAHs) and is able to function as a living bioluminescent reporter for the presence of naphthalene contamination, its bioavailability, and the functional process of biodegradation. A unique component of this field investigation was the availability of an array of large subsurface soil lysimeters. This article describes the experience associated with the release of a genetically modified microorganism, the lysimeter facility and its associated instrumentation, as well as representative data collected during the first eighteen months of operation.

POLYCYCLIC AROMATIC HYDROCARBON EMISSION IN THE PROPLYD HST10: WHAT IS THE MECHANISM BEHIND PHOTOEVAPORATION?  

SciTech Connect (OSTI)

Proplyds are photodissociation-region-(PDR)-like cometary cocoons around young stars which are thought to originate through photoevaporation of the central protoplanetary disk by external UV radiation from the nearby OB stars. This Letter presents spatially resolved mid-infrared imaging and spectroscopy of the proplyd HST10 obtained with the Very Large Telescope/VISIR instrument. These observations allow us to detect polycyclic aromatic hydrocarbon (PAH) emission in the proplyd PDR and to study the general properties of PAHs in proplyds for the first time. We find that PAHs in HST10 are mostly neutral and at least 50 times less abundant than typical values found for the diffuse interstellar medium or the nearby Orion Bar. With such a low PAH abundance, photoelectric heating is significantly reduced. If this low abundance pertains also to the original disk material, gas heating rates could be too low to efficiently drive photoevaporation unless other processes can be identified. Alternatively, the model behind the formation of proplyds as evaporating disks may have to be revised.

Polyphenoloxidases immobilized in organic gels: Properties and applications in the detoxification of aromatic compounds  

SciTech Connect (OSTI)

Gelatine gels originate from water in oil microemulsions in which the ternary system consists of isooctane/sulfosuccinic acid bis [2-ethyl hexyl] ester/water; the solubilization of gelatin in the water pool of these microemulsions transforms them into viscous gels in which it is possible to cosolubilize various reactive molecules. These gels were used to immobilize two phenoloxidases, a laccase from Trametes versicolor and a tyrosinase from mushroom. The best balance between gel retention and catalytic activity was reached at a gelatine concentration of 2.5% (w/v) in the case of tyrosinase, while laccase immobilization was independent of gelatine concentration. Both enzymes kept the same optimum pH as the corresponding soluble controls, while a partial loss of activity was observed when they were immobilized. Immobilized enzymes showed an increased stability when incubated for several days at 4 C with a very low release from the gels in the incubation solutions. The immobilization of tyrosinase and of laccase enhanced stability to thermal inactivation. Furthermore, gel-entrapped tyrosinase was almost completely preserved from proteolysis: more than 80% of the activity was maintained, while only 25% of the soluble control activity was detected after the same proteolytic treatments. A column packed with gel-immobilized tyrosinase was used to demonstrate that enzymes immobilized with this technique may be reused several times in the same reaction without loosing their efficiency. Finally, gel-entrapped tyrosinase and laccase were capable of removing naturally occurring and xenobiotic aromatic compounds from aqueous suspensions with different degrees of efficiency.

EXTINCTION AND POLYCYCLIC AROMATIC HYDROCARBON INTENSITY VARIATIONS ACROSS THE H II REGION IRAS 12063-6259  

SciTech Connect (OSTI)

The spatial variations in polycyclic aromatic hydrocarbon (PAH) band intensities are normally attributed to the physical conditions of the emitting PAHs, however in recent years it has been suggested that such variations are caused mainly by extinction. To resolve this question, we have obtained near-infrared (NIR), mid-infrared (MIR), and radio observations of the compact H II region IRAS 12063-6259. We use these data to construct multiple independent extinction maps and also to measure the main PAH features (6.2, 7.7, 8.6, and 11.2 {mu}m) in the MIR. Three extinction maps are derived: the first using the NIR hydrogen lines and case B recombination theory; the second combining the NIR data with radio data; and the third making use of the Spitzer/IRS MIR observations to measure the 9.8 {mu}m silicate absorption feature using the Spoon method and PAHFIT (as the depth of this feature can be related to overall extinction). The silicate absorption over the bright, southern component of IRAS 12063-6259 is almost absent while the other methods find significant extinction. While such breakdowns of the relationship between the NIR extinction and the 9.8 {mu}m absorption have been observed in molecular clouds, they have never been observed for H II regions. We then compare the PAH intensity variations in the Spitzer/IRS data after dereddening to those found in the original data. It was found that in most cases, the PAH band intensity variations persist even after dereddening, implying that extinction is not the main cause of the PAH band intensity variations.

Phototransformation of Polycyclic Aromatic Hydrocarbons (PAHs) on a Non-Semi Conductive Surface Such as Silica  

SciTech Connect (OSTI)

Polycyclic aromatic hydrocarbons (PAH), by products of fossil fuel production and consumption, constitute a large class of environmental pollutants. These toxic and sometimes carcinogenic compounds are also found in coal tar and fly ash. When released into the air, they can be sorbed onto particulates present in the atmosphere where they find their way into soil and ground water upon being washed by rain. During their residence time in the environment, PAHs will be exposed to solar radiation and may undergo phototransformation to other products. Thus, light induced photodegradation of PM`s at the solid/air interfaces can play a significant role in their depletion. Light-induced processes have been claimed to enhance transformation of these PM`s in the environment. However, detailed studies on the nature and identities of photoproducts formed during the transformation of these compounds on solid surfaces is scarce. Since insulators such as silica, alumina,silicoaluminates and calcium carbonate are believed to constitute up 20-30% of inorganic particulates present in the atmosphere, they serve as environmentally relevant model surfaces to study the photophysical and photochemical behavior of PM`s. Although photochemistry of organic compounds adsorbed on solid surfaces has received much attention in recent years, the specific properties of the interface which influence photoprocesses and the exact mechanism of interaction between a surface and a substrate are often not well understood. We have investigated the photochemistry of many PAHs including eight that are on Environmental Protection Agency`s (EPA) sixteen priority pollutant PAH list shown in Table 1 at silica/air interface.

Reaction mechanisms in aromatic hydrocarbon formation involving the C{sub 5}H{sub 5} cyclopentadienyl moiety  

SciTech Connect (OSTI)

The quantum chemical BAC-MP4 and BAC-MP2 methods have been used to investigate the reaction mechanisms leading to polycyclic aromatic hydrocarbon (PAH) ring formation. In particular the authors have determined the elementary reaction steps in the conversion of two cyclopentadienyl radicals to naphthalene. This reaction mechanism is shown to be an extension of the mechanism occurring in the H atom-assisted conversion of fulvene to benzene. The net reaction involves the formation of dihydrofulvalene, which eliminates a hydrogen atom and then rearranges to form naphthalene through a series of ring closures and openings. The importance of forming the {single_bond}CR({center_dot}){single_bond}CHR{single_bond}CR{prime}{double_bond}CR{double_prime}-moiety, which can undergo rearrangement to form three-carbon-atom ring structures, is illustrated with the C{sub 4}H{sub 7} system. The ability of hydrogen atoms to migrate around the cyclopentadienyl moiety is illustrated both for methyl-cyclopentadiene, C{sub 5}H{sub 5}CH{sub 3}, and dihydrofulvalene, C{sub 5}H{sub 5}C{sub 5}H{sub 5}, as well as for their radical species, C{sub 6}H{sub 7} and C{sub 5}H{sub 5}C{sub 5}H{sub 4}. The mobility of hydrogen in the cyclopentadienyl moiety plays an important role both in providing resonance-stabilized radical products and in creating the {single_bond}CR({center_dot}){single_bond}CHR{single_bond}CR{prime}{double_bond}CR{double_prime}-moiety for ring formation. The results illustrate the radical pathway for converting five-membered rings to aromatic six-membered rings. Furthermore, the results indicate the important catalytic role of H atoms in the aromatic ring formation process.

Liquid-liquid equilibria for mixtures of an alkane + an aromatic hydrocarbon + 1,4-dicyanobutane at 298.15 K  

SciTech Connect (OSTI)

The separation of pure aromatic and aliphatic compounds from their mixtures is an important goal in chemical operations (e.g., Fischer-Tropsch synthesis) that produce both types of compounds. In this work the authors have used 1,4-dicyanobutane (DCB) as a potential solvent for this separation. Liquid-liquid equilibrium results for mixtures of an alkane + an aromatic hydrocarbon + 1,4-dicyanobutane at 298.15 K are reported, where the alkane is hexane or nonane or dodecane or hexadecane and the aromatic hydrocarbon is benzene or methylbenzene or 1,2-dimethylbenzene, or 1,3-dimethylbenzene, or 1,4-dimethylbenzene or 1,3,5-trimethylbenzene or ethylbenzene. The results show that there is a small increase in the two-phase region as the chain length of the alkane is increased. The type of aromatic hydrocarbon present in the mixture has a noticeable effect on the slopes of the tie lines. There is also an increase in the area of the two phase-region with increasing substitution of methyl groups on the benzene ring. NRTL and UNIQUAC models were correlated to the data. The results show that 1,4-dicyanobutane may be used as a solvent for the separation of aromatic and aliphatic hydrocarbons.

INFRARED LUMINOSITIES AND AROMATIC FEATURES IN THE 24 {mu}m FLUX-LIMITED SAMPLE OF 5MUSES  

SciTech Connect (OSTI)

We study a 24 {mu}m selected sample of 330 galaxies observed with the infrared spectrograph for the 5 mJy Unbiased Spitzer Extragalactic Survey. We estimate accurate total infrared luminosities by combining mid-IR spectroscopy and mid-to-far infrared photometry, and by utilizing new empirical spectral templates from Spitzer data. The infrared luminosities of this sample range mostly from 10{sup 9} L{sub sun} to 10{sup 13.5} L{sub sun}, with 83% in the range 10{sup 10} L{sub sun} < L{sub IR} < 10{sup 12} L{sub sun}. The redshifts range from 0.008 to 4.27, with a median of 0.144. The equivalent widths of the 6.2 {mu}m aromatic feature have a bimodal distribution, probably related to selection effects. We use the 6.2 {mu}m polycyclic aromatic hydrocarbon equivalent width (PAH EW) to classify our objects as starburst (SB)-dominated (44%), SB-AGN composite (22%), and active galactic nucleus (AGN)-dominated (34%). The high EW objects (SB-dominated) tend to have steeper mid-IR to far-IR spectral slopes and lower L{sub IR} and redshifts. The low EW objects (AGN-dominated) tend to have less steep spectral slopes and higher L{sub IR} and redshifts. This dichotomy leads to a gross correlation between EW and slope, which does not hold within either group. AGN-dominated sources tend to have lower log(L{sub PAH7.7{sub {mu}m}}/L{sub PAH11.3{sub {mu}m}}) ratios than star-forming galaxies, possibly due to preferential destruction of the smaller aromatics by the AGN. The log(L{sub PAH7.7{sub {mu}m}}/L{sub PAH11.3{sub {mu}m}}) ratios for star-forming galaxies are lower in our sample than the ratios measured from the nuclear spectra of nearby normal galaxies, most probably indicating a difference in the ionization state or grain size distribution between the nuclear regions and the entire galaxy. Finally, we provide a calibration relating the monochromatic continuum or aromatic feature luminosity to L{sub IR} for different types of objects.

Supersymmetry and CP violation in B{sub s}{sup 0}-B{sub s}{sup 0} mixing and B{sub s}{sup 0}{yields}J/{psi}{phi} decay  

SciTech Connect (OSTI)

Supersymmetric contributions to time independent asymmetry in B{sub s}{sup 0}{yields}J/{psi}{phi} process are analyzed in view of recent Tevatron experimental measurements. We show that the experimental limits of the mass difference {delta}M{sub B{sub s}} and the mercury electric dipole moment significantly constrain the supersymmetric (SUSY) contribution to B{sub s}{sup 0}-B{sub s}{sup 0} mixing, so that sin2{beta}{sub s} < or approx. 0.1. We also point out that the one loop SUSY contribution to B{sub s}{sup 0}{yields}J/{psi}{phi} decay can be important and can lead to large indirect CP asymmetries which are different for different polarization states. These new physics effects in the decay amplitude can be consistent with CP measurements in the B{sub d} system.

Size exclusion chromatography for the unambiguous detection of aliphatics in fractions from petroleum vacuum residues, coal liquids, and standard materials, in the presence of aromatics  

SciTech Connect (OSTI)

A method has been developed using size exclusion chromatography (SEC) in heptane eluent that can detect aliphatics unambiguously without fractionation to remove aromatics. Spherical molecules such as colloidal silicas elute at the exclusion limit, while alkanes up to C{sub 50} elute through the porosity of the column. Detection of aliphatics was defined by use of an evaporative light scattering (ELS) detector with the simultaneous absence of UV absorbance at 300 nm. Alkanes smaller than C{sub 12} were not detected because the conditions of operation of the ELS caused their evaporation. All aromatics eluted after the permeation limit of about 25 min and were not detected until well after 45 min by their UV absorbance. The SEC method was applied to petroleum vacuum residues and coal liquids, and their fractions were soluble in pentane or heptane. High-temperature (HT) GC-MS confirmed the presence of alkanes in the pentane- and heptane-soluble fractions of petroleum vacuum residues, but did not elute any of the aromatics known to be present from SEC. Alkanes were examined in pentane-soluble fractions of a coal digest and a low-temperature coal tar; alkanes up to C{sub 40} were detected in the low-temperature tar and, although present in the digest, were masked by aromatics. No alkanes were detected by either SEC or HT GC-MS in fractions from a coal tar pitch. Aromatics in coal liquids and one petroleum residue were also examined by SEC using NMP as eluent and by UV fluorescence spectroscopy. The SEC method will find application to pentane- and heptane-soluble fractions of petroleum liquids and coal liquids where the alkanes are concentrated relative to the more abundant aromatics. 43 refs., 10 figs., 2 tabs.

New analytical approaches for determination of 1) tricyclic aromatics, 2) alkenes, and weight % data in Naval diesel fuels are described. Tricyclic aromatics are detected and characterized at concentrations as low as approx. 0.25% in diesel fuels. Various analytical approaches for characterizing alkenes in diesel fuels are also explored, including: 1) chromatographic separation of the alkene fraction in diesel fuels by AgNO/sub 3/ impregnated chromatographic columns, and 2) a /sup 19/F NMR tagging method characterizing alkenes. Finally, a calculative method for conversion of LC-1H NMR molar data to weight % data for each chromatographic fraction in a fuel is described.

UV-vis spectra of singlet state cationic polycyclic aromatic hydrocarbons: Time-dependent density functional theory study  

SciTech Connect (OSTI)

A theoretical study of singlet state cations of polycyclic aromatic hydrocarbons is performed. Appropriate symmetry suitable for further calculations is chosen for each of the systems studied. The excitation states of such species are obtained by the time dependent density functional theory (TD-DFT) method. The computations are performed using both Pople and electronic response properties basis sets. The results obtained with the use of different basis sets are compared. The electronic transitions are described and the relationships for the lowest-lying transitions states of different species are found. The properties of in-plane and out-of-plane transitions are also delineated. The TD-DFT results are compared with the experimental data available.

A uniform, comprehensive theoretical interpretation of spectroscopic data is presented for 53 radical ion species of polycyclic aromatic hydrocarbons (PAH’s) with the aid of (Tamm–Dancoff) time-dependent density functional theory (TDDFT). TDDFT is capable of predicting the transition energies to the low-lying excited states of PAH ions with quantitative accuracy (the standard deviation from experimental results being less than 0.3 eV) and their intensity patterns qualitatively correctly. The accuracy is hardly affected by the sizes of PAH ions (azulene through dinaphthocoronene), the types of transitions (Koopmans or satellite transitions), the types of orbi-tals involved (*←, *←, or *← transitions), the types of ions (cations or anions), or other geometrical or electronic perturbations (non-planarity, sp3 carbons, or heterocyclic or non-benzenoid rings)

Influence of co-attached aromatics on the thermolysis of surface-immobilized 1,3-diphenylpropane  

SciTech Connect (OSTI)

The technique of model compound immobilization by covalent surface attachment is being employed to investigate the potential impact of restricted diffusional mobility on the thermal reactivity of coal. This restricted mobility may be imposed in coal as a consequence of its cross-linked, macromolecular structure. Thermolysis studies at 345--400{degree}C of model coal structures covalently attached to a silica surface have shown that significant perturbations in free-radical reaction mechanisms can occur, and result in altered reaction rates and product distributions compared with corresponding fluid phase behavior. In the current study, we are beginning to probe the influence of the structure of co-attached aromatic molecules such as biphenyl and diphenylmethane on the reaction rate and regioselectivity in the thermolysis of surface-attached 1,3-diphenylpropane. 6 refs., 1 tab.

Measurement of the CP-Violating Phase beta_s in B0s -> J/Psi Phi Decays with the CDF II Detector  

SciTech Connect (OSTI)

We present a measurement of the \\CP-violating parameter \\betas using approximately 6500 $\\BsJpsiPhi$ decays reconstructed with the CDF\\,II detector in a sample of $p\\bar p$ collisions at $\\sqrt{s}=1.96$ TeV corresponding to 5.2 fb$^{-1}$ integrated luminosity produced by the Tevatron Collider at Fermilab. We find the \\CP-violating phase to be within the range $\\betas \\in [0.02, 0.52] \\cup [1.08, 1.55]$ at 68% confidence level where the coverage property of the quoted interval is guaranteed using a frequentist statistical analysis. This result is in agreement with the standard model expectation at the level of about one Gaussian standard deviation. We consider the inclusion of a potential $S$-wave contribution to the $\\Bs\\to J/\\psi K^+K^-$ final state which is found to be negligible over the mass interval $1.009 < m(K^+K^-)<1.028 \\gevcc$. Assuming the standard model prediction for the \\CP-violating phase \\betas, we find the \\Bs decay width difference to be $\\deltaG = 0.075 \\pm 0.035\\,\\textrm{(stat)} \\pm 0.006\\,\\textrm{(syst)} \\ps$. We also present the most precise measurements of the \\Bs mean lifetime $\\tau(\\Bs) = 1.529 \\pm 0.025\\,\\textrm{(stat)} \\pm 0.012\\,\\textrm{(syst)}$ ps, the polarization fractions $|A_0(0)|^2 = 0.524 \\pm 0.013\\,\\textrm{(stat)} \\pm 0.015\\,\\textrm{(syst)}$ and $|A_{\\parallel}(0)|^2 = 0.231 \\pm 0.014\\,\\textrm{(stat)} \\pm 0.015\\,\\textrm{(syst)}$, as well as the strong phase $\\delta_{\\perp}= 2.95 \\pm 0.64\\,\\textrm{(stat)} \\pm 0.07\\,\\textrm{(syst)} \\textrm{rad}$. In addition, we report an alternative Bayesian analysis that gives results consistent with the frequentist approach.

Manganese peroxidase mRNA and enzyme activity levels during bioremediation of polycyclic aromatic hydrocarbon-contaminated soil with Phanerochaete chrysosporium  

SciTech Connect (OSTI)

mRNA extraction from soil and quantitation by competitive reverse transcription-PCR were combined to study the expression of three manganese peroxidase (MnP) genes during removal of polycyclic aromatic hydrocarbons from cultures of Phanerochaete chrysosporium grown in presterilized soil. Periods of high mnp transcript levels and extractable MnP enzyme activity were temporally correlated, although separated by a short (1- to 2-day) lag period. This time frame also coincided with maximal rates of fluorene oxidation and chrysene disappearance in soil cultures, supporting the hypothesis that high ionization potential polycyclic aromatic hydrocarbons are oxidized in soil via MnP-dependent mechanisms. The patterns of transcript abundance over time in soil-grown P. chrysosporium were similar for all three of the mnp mRNAs studied, indicating that transcription of this gene family may be coordinately regulated under these growth conditions. 47 refs., 6 figs., 1 tab.

Analysis of Nitro-Polycyclic Aromatic Hydrocarbons in Conventional Diesel and Fischer--Tropsch Diesel Fuel Emissions Using Electron Monochromator-Mass Spectrometry  

SciTech Connect (OSTI)

The presence of nitro-polycyclic aromatic hydrocarbons (NPAHs) in diesel fuel emissions has been studied for a number of years predominantly because of their contribution to the overall health and environmental risks associated with these emissions. Electron monochromator-mass spectrometry (EM-MS) is a highly selective and sensitive method for detection of NPAHs in complex matrixes, such as diesel emissions. Here, EM-MS was used to compare the levels of NPAHs in fuel emissions from conventional (petroleum) diesel, ultra-low sulfur/low-aromatic content diesel, Fischer-Tropsch synthetic diesel, and conventional diesel/synthetic diesel blend. The largest quantities of NPAHs were detected in the conventional diesel fuel emissions, while the ultra-low sulfur diesel and synthetic diesel fuel demonstrated a more than 50% reduction of NPAH quantities when compared to the conventional diesel fuel emissions. The emissions from the blend of conventional diesel with 30% synthetic diesel fuel also demonstrated a more than 30% reduction of the NPAH content when compared to the conventional diesel fuel emissions. In addition, a correlation was made between the aromatic content of the different fuel types and NPAH quantities and between the nitrogen oxides emissions from the different fuel types and NPAH quantities. The EM-MS system demonstrated high selectivity and sensitivity for detection of the NPAHs in the emissions with minimal sample cleanup required.

Source Contribution Analysis of Surface Particulate Polycyclic Aromatic Hydrocarbon Concentrations in Northeastern Asia by Source-receptor Relationships  

SciTech Connect (OSTI)

We analyzed the sourceereceptor relationships for particulate polycyclic aromatic hydrocarbon (PAH) concentrations in northeastern Asia using an aerosol chemical transport model. The model successfully simulated the observed concentrations. In Beijing (China) benzo[a]pyren (BaP) concentrations are due to emissions from its own domain. In Noto, Oki and Tsushima (Japan), transboundary transport from northern China (>40N, 40-60%) and central China (30-40N, 10-40%) largely influences BaP concentrations from winter to spring, whereas the relative contribution from central China is dominant (90%) in Hedo. In the summer, the contribution from Japanese domestic sources increases (40-80%) at the 4 sites. Contributions from Japan and Russia are additional source of BaP over the northwestern Pacific Ocean in summer. The contribution rates for the concentrations from each domain are different among PAH species depending on their particulate phase oxidation rates. Reaction with O3 on particulate surfaces may be an important component of the PAH oxidation processes.

Dispersion modeling of polycyclic aromatic hydrocarbons from combustion of biomass and fossil fuels and production of coke in Tianjin, China  

SciTech Connect (OSTI)

A USEPA procedure, ISCLT3 (Industrial Source Complex Long-Term), was applied to model the spatial distribution of polycyclic aromatic hydrocarbons (PAHs) emitted from various sources including coal, petroleum, natural gas, and biomass into the atmosphere of Tianjin, China. Benzo(a)pyrene equivalent concentrations (BaPeq) were calculated for risk assessment. Model results were provisionally validated for concentrations and profiles based on the observed data at two monitoring stations. The dominant emission sources in the area were domestic coal combustion, coke production, and biomass burning. Mainly because of the difference in the emission heights, the contributions of various sources to the average concentrations at receptors differ from proportions emitted. The shares of domestic coal increased from {approximately} 43% at the sources to 56% at the receptors, while the contributions of coking industry decreased from {approximately} 23% at the sources to 7% at the receptors. The spatial distributions of gaseous and particulate PAHs were similar, with higher concentrations occurring within urban districts because of domestic coal combustion. With relatively smaller contributions, the other minor sources had limited influences on the overall spatial distribution. The calculated average BaPeq value in air was 2.54 {+-} 2.87 ng/m{sup 3} on an annual basis. Although only 2.3% of the area in Tianjin exceeded the national standard of 10 ng/m{sup 3}, 41% of the entire population lives within this area. 37 refs., 9 figs.

Atmospheric deposition of polycyclic aromatic hydrocarbons in an urban and a suburban area of Korea from 2002 to 2004  

SciTech Connect (OSTI)

Atmospheric bulk samples (wet and dry) were collected monthly during 2002 to 2004 from an urban and a suburban area in Korea for assessment of depositional flux and seasonal variations in the concentrations of polycyclic aromatic hydrocarbons (PAHs). PAH depositional flux ranged from 64.1 to 610 {mu} g/m{sup 2}/y for the urban area and from 65 to 460 {mu} g/m{sup 2}/y for the suburban area. The fluxes of PAHs measured in this study were comparable with those reported for urban and suburban areas in other countries. The fluxes of particulates and PAHs were higher in winter than in summer, consistent with the greater per capita consumption of fossil fuel in winter than in summer. Ambient temperature played a major role in the seasonal variability in PAH fluxes. Photochemical degradation of PAHs appears to occur during the summer months. The relationship of PAH depositional fluxes with major air pollutants, such as ozone, sulfur dioxide, carbon monoxide, nitrogen dioxide, and presence of particulate matter up to 10 {mu} m in size (PM10), was also investigated. Dominant PAH compounds in both the urban and the suburban locations were benzo(g,h,i)perylene, pyrene, and indeno(1,2,3-c,d)pyrene. Based on the PAH diagnostic ratios and a factor analysis, the major sources of PAHs in the urban and the suburban regions were found to be similar. Diesel exhaust, coal combustion, and gasoline emissions contributed predominantly to atmospheric PAH contamination.

POLYCYCLIC AROMATIC HYDROCARBONS IN GALAXIES AT z approx 0.1: THE EFFECT OF STAR FORMATION AND ACTIVE GALACTIC NUCLEI  

SciTech Connect (OSTI)

We present the analysis of the polycyclic aromatic hydrocarbon (PAH) spectra of a sample of 92 typical star-forming galaxies at 0.03 < z < 0.2 observed with the Spitzer intensified Reticon spectrograph (IRS). We compare the relative strengths of PAH emission features with Sloan Digital Sky Survey optical diagnostics to probe the relationship between PAH grain properties and star formation and active galactic nuclei (AGNs) activity. Short-to-long wavelength PAH ratios, and in particular the 7.7 mum-to-11.3 mum feature ratio, are strongly correlated with the star formation diagnostics D{sub n} (4000) and Halpha equivalent width, increasing with younger stellar populations. This ratio also shows a significant difference between active and non-active galaxies, with the active galaxies exhibiting weaker 7.7 mum emission. A hard radiation field as measured by [O{sub III}]/Hbeta and [Ne{sub III}]{sub 15.6m}u{sub m}/[Ne{sub II}]{sub 12.8m}u{sub m} effects PAH ratios differently depending on whether this field results from starburst activity or an AGN. Our results are consistent with a picture in which larger PAH molecules grow more efficiently in richer media and in which smaller PAH molecules are preferentially destroyed by the AGN.

Non-Markovian response of ultrafast coherent electronic ring currents in chiral aromatic molecules in a condensed phase  

SciTech Connect (OSTI)

Results of a theoretical study on non-Markov response for femtosecond laser-driven coherent ring currents in chiral aromatic molecules embedded in a condensed phase are presented. Coherent ring currents are generated by coherent excitation of a pair of quasi-degenerated ?-electronic excited states. The coherent electronic dynamical behaviors are strongly influenced by interactions between the electronic system and phonon bath in a condensed phase. Here, the bath correlation time is not instantaneous but should be taken to be a finite time in ultrashort time-resolved experiments. In such a case, Markov approximation breaks down. A hierarchical master equation approach for an improved semiclassical Drude dissipation model was adopted to examine the non-Markov effects on ultrafast coherent electronic ring currents of (P)-2,2{sup ?}-biphenol in a condensed phase. Time evolution of the coherent ring current derived in the hierarchical master equation approach was calculated and compared with those in the Drude model in the Markov approximation and in the static limit. The results show how non-Markovian behaviors in quantum beat signals of ring currents depend on the Drude bath damping constant. Effects of temperatures on ultrafast coherent electronic ring currents are also clarified.

Accumulation and effects of aluminum smelter-generated polycyclic aromatic hydrocarbons on soft-bottom invertebrates and fish  

SciTech Connect (OSTI)

An integrated study involving measurements of polycyclic aromatic hydrocarbon (PAH) levels in bottom sediments, assessments of resident soft-bottom communities, the accumulation of PAHs in soft-bottom invertebrates, and biomarker responses in invertebrates and fish was conducted to assess the impact of an aluminum reduction plant in a Norwegian fjord. The fjord sediments were heavily contaminated by PAHs in the inner reaches near the aluminum smelter, where concentrations were well above levels elsewhere reported to induce biological effects. Nevertheless, the PAH contamination in the fjord did not seem to have severe effects on the benthic biota. This conclusion can be drawn from the soft-bottom communities as well as from biomarker analyses. Presumably, contaminant speciation is important for explaining the restricted biological effects. The results support the assumption that PAHs associated with soot-like structures have limited bioavailability. They also point to the need to link various single-species approaches to measurements of effects on higher levels of organization and with an understanding of the speciation of the chemical contaminant.

POLYCYCLIC AROMATIC HYDROCARBONS, IONIZED GAS, AND MOLECULAR HYDROGEN IN BRIGHTEST CLUSTER GALAXIES OF COOL-CORE CLUSTERS OF GALAXIES  

SciTech Connect (OSTI)

We present measurements of 5-25 {mu}m emission features of brightest cluster galaxies (BCGs) with strong optical emission lines in a sample of nine cool-core clusters of galaxies observed with the Infrared Spectrograph on board the Spitzer Space Telescope. These systems provide a view of dusty molecular gas and star formation, surrounded by dense, X-ray-emitting intracluster gas. Past work has shown that BCGs in cool-core clusters may host powerful radio sources, luminous optical emission-line systems, and excess UV, while BCGs in other clusters never show this activity. In this sample, we detect polycyclic aromatic hydrocarbons (PAHs), extremely luminous, rotationally excited molecular hydrogen line emission, forbidden line emission from ionized gas ([Ne II] and [Ne III]), and infrared continuum emission from warm dust and cool stars. We show here that these BCGs exhibit more luminous forbidden neon and H{sub 2} rotational line emission than star-forming galaxies with similar total infrared luminosities, as well as somewhat higher ratios of 70 {mu}m/24 {mu}m luminosities. Our analysis suggests that while star formation processes dominate the heating of the dust and PAHs, a heating process consistent with suprathermal electron heating from the hot gas, distinct from star formation, is heating the molecular gas and contributing to the heating of the ionized gas in the galaxies. The survival of PAHs and dust suggests that dusty gas is somehow shielded from significant interaction with the X-ray gas.
